No prime numbers end in 0. 130 is a composite.
101 103 107 109 113 127
You can easily work it out. firstly, you know that the even numbers are not prime, so that leaves only ~15 numbers. You can check out each number. [hint you only have to test for factors of a number up to the square root of the number.]
The prime numbers between 130 and 140 are 131, 137, and 139.
127
The prime numbers between 100 and 130 are 101, 103, 107, 109, 113, 127. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this range, we identify the prime numbers by checking if they are only divisible by 1 and themselves.

131, 137 and 139
No prime numbers end in 0. 130 is a composite.
101 103 107 109 113 127
The prime numbers between 110 and 130 are 113, 127. Prime numbers are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. To determine if a number is prime, we need to check if it is divisible by any number other than 1 and itself. In this case, 111, 115, 117, 119, 121, 123, 125, and 129 are not prime as they have divisors other than 1 and themselves.
They are the numbers that have more than two factors whereas prime numbers have only two factors
There are 11 numbers between 1 and 130 that have an odd number of factors: 1,4,9,16,25,36,49,64,81,100,121.
