A triangle
It is 97. it is largest, because it is the largest double digit prime number.
But you do know the factors of prime numbers. Every prime number has two factors: one and the number itself.
Memorize them all.
what is a prime factorization ok here ill tell you and ill give u an example of prime factorization example:2,3,4.5.7.9.11 mostlyits an odd number but the number 2 is not an odd number buts its prime
You could figure out a prime number by the help of its factors. If it has only 2 factors which are 1 and number itself, then it is prime.
A triangle
the number can be divided without a remainder

Count the number of twos in its prime factorization.

Well, lets first ask, What is a Prime Number? A Prime Number is a number that can only be multiplied by 1 and itself. So how do you find out what is a prime number? This is an example of a prime number:17. Try to multiply numbers and see if you get 17. You won't. 17 can only be multiplied by 1 and itself. So that's why it is a prime number. Pick a number in the future and try to multiply to it. If you don't get that number as an answer, its a prime number, if you get it as an answer, it is NOT a prime number.
There is no quick way to work out if a number is prime or not, the only way is to see if it can be divided by any numbers that aren't itself or one.
156 is a not a prime number. A prime number is a number that only can divided by 1 and itself. Examples of Primes is 1, 2,3, 5, 7, 11, 13, 17.......................... 156 factors include 1,2,3,4,6,12,13,26,39,52,78,156. A easy way to figure out if a prime number is a prime number or not look and see if the last digit in the number. If the digit is even is it not a prime number.
A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.
