220 = 2 x 2 x 5 x 11
Prime numbers don't factorize; they're already prime.
No, 220 is not a prime number.
220 is a composite number, as are all whole numbers ending in zero.
220 is not a prime number because it is divisible by a number other than itself and the number 1. No even number other than 2 is a prime because they can all be divided by 2.
211 is the only prime number between 200 and 220
If you play the factor game, you factorize the number. If the number of factors are only 2 including 1 and number itself, then it is a prime.
break it into prime number multiples,10 = 2 * 5 (both prime numbers)example: factorize 387(387) = 9 * 43 (both primes , end of excercise)factorize 390:(390) = 2 * (195) = 3 * (65) = 5 * 13 (both primes , end of excercise)
3 times 5
The prime factorization of 220 is 2x2x5x11.
Only 43 and 107 are prime numbers
The prime factors of 220 are: 2,5,11
It's more efficient. You want to end up with all prime numbers. You could divide by a composite number, but you'd just have to break that number down later. It saves steps.
