 # Prime Numbers Up To 100

Prime numbers up to 100 are the prime numbers that separate 1 and 100. Any whole number which is more noteworthy than 1 and it is divisible exclusively by 1 and the actual number, is known as a prime number. The equation of prime numbers helps in addressing the general type of a prime number. Allow us to figure out how to figure out the prime numbers up to 100 by Eratosthenes’ technique, and take a look at the rundown of prime numbers up to 100.

## Definition Of Prime Numbers

Natural numbers that have just two factors, or at least, one, and the actual number are known as prime numbers. We realise that a component is a number that partitions the given number. At the end of the day, on the off chance that a number can’t be separated into equivalent gatherings, then it is a prime number. We can isolate a number into bunches with equivalent numbers of things provided that it tends to be factored as a result of two numbers. For instance, 3 can’t be separated into gatherings of equivalent numbers. This is because 3 must be factored as follows:

3 × 1 = 3

1 × 3 = 3

There are just two elements of 3, or at least, one, and the actual number, consequently, 3 is a prime number. It is to be noticed that the number 1 is neither a prime number nor a composite number.

## Significant Notes

1. Prime numbers are natural numbers more noteworthy than 1, that have just two variables, one and the actual number.
2. A number can be a prime number if it is not zero or a whole number.
3. Prime factorization is a strategy to track down prime numbers.

## How can we find Prime Numbers Up to 100

We can find prime numbers in arithmetic by utilising an old procedure which is the sieve of Eratosthenes. It is an old technique for tracking down every one of the prime numbers up to some random breaking point. The accompanying advances tell the best way to track down every one of the prime numbers up to 100 by Eratosthenes’ technique. Leave the number 1 as all prime numbers are more prominent than one.

Step 1: First make a rundown of whole numbers from 2 to 100.

Step 2: The number 2 is the principal number in the rundown and it is a prime number as well; cross out each second number in the rundown after 2 by adding 2 or skip counting by 2s. For instance, 2 + 2 = 4, 4 + 2 = 6, etc (these will be every one of the products of 2 in the rundown): Such as 4, 6, 8, 10, 12, 14, 16, etc up to 100.

Step 3: 3 is the following number in the rundown later; cross out each third number in the rundown after 3 by adding 3 or skip counting by 3s. For instance, 3 + 3 = 6, 6 + 3 = 9, etc (these will be every one of the products of 3 in the rundown): Such as 6, 9,12, 15, 18, 21, 24, etc up to 100.

Step 4: 5 is the following number in the rundown after 3; cross out each fifth number in the rundown after 5 by adding 5 or skip counting by 5s. For instance, 5 + 5 = 10, 10 + 5 = 15, etc (these will be every one of the products of 5 in the rundown): Such as 10, 15, 20, 25, 30, etc up to 100.

Step 5: 7 is the following number in the rundown after 5; the subsequent stage is to cross out each seventh number in the rundown after 7, by adding 7 or skip counting by 7s. For instance, 7 + 7 = 14, 14 + 7 = 21, etc (these will be every one of the products of 7 in the rundown) like 14, 21, 28, 35, 42, 49, 56, 63, etc up to 100.

## List Of Prime Numbers

• Prime numbers somewhere in the range of 1 and 10

2, 3, 5, 7

• Prime numbers somewhere in the range of 11 and 20

11, 13, 17, 19

• Prime numbers somewhere in the range of 21 and 30

23, 29

• Prime numbers somewhere in the range of 31 and 40

31, 37

• Prime numbers somewhere in the range of 41 and 50

41, 43, 47

• Prime numbers somewhere in the range of 51 and 100

53, 59, 61, 67, 71, 73, 79, 83, 89, 97

Along these lines, there are all out 25 prime numbers up to 100. Accordingly, the prime numbers 1 to 100 can be recorded as,

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

## Realities on prime numbers 1 to 100

• 2 is the main even prime number and the leftover even numbers are not prime numbers as they can be separated by 2.
• Any prime number more noteworthy than 5 and finishes with a 5 can be separated by 5 so it can’t be a prime number.
• Prime numbers have precisely two factors in this manner 0 and 1 are not prime numbers.
