I THINK... you see if it can be either multiplied or divided by any other number but 1, and if you can divide or multiply by any other number it is composite, if it cant be divided or multiplied, it is prime...
I think you mean that the prime factorization is 2 times 3 times 5. To solve, just perform the multiplication: 2x3x5=30
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
53 is a prime number so there is no relevant prime factorization for it.
The only number with that prime factorization has to be 48.
Yes. Any prime number greater than 100 has only itself in its prime factorization. Examples: The prime factorization of 101 is 101. The prime factorization of 109 is 109. The prime factorization of 127 is 127. The prime factorization of 311 is 311. The prime factorization of 691 is 691.
91 cannot be in the prime factorization of any number because it is not a prime number itself.
When all the factors are prime numbers, that's a prime factorization.
421 is a prime number so it does not have prime factorization.
19 is a prime number, so it has no prime factorization.
Since 89 is a prime number, the prime factorization of the number is simply 89.

An easy way to find the prime factorization of a number is to find the lowest prime number that is a divisor of that number, and perform a division. By repeating this process, you collect the prime factorization of your original number. For example: 88 is divisible by 2, which is the lowest prime number we can divide it by. 88/2 = 44 44 is divisble by 2 again 44 / 2 = 22 22 is STILL divisible by 2 22 / 2 = 11 and now we have the number 11, which is prime so we stop. Our prime factorization is therefore three 2's and an 11: 2, 2, 2, 11
