Explain why you cannot find the prime factor derivation of 4.8
Ymorist [56]
"Prime Factorization" is finding which prime numbers multiply together to make the original number.

Because prime numbers are all whole numbers (no decimals), there is no way to get a product of prime numbers that is a decimal like 4.8.

In other words, because 4.8 is not a positive whole number, you can't find its prime factorization.
