Dawson Buckley · Answer 1

Answer: 2,2,2,2,5

Step-by-step explanation:

You could start by thinking of two factors of ten like 8*10=80 or 16*5=80

Then factor those factors. 8 is 2*2*2 and 10 is 2*5. OR 16 is 2*2*2*2 and 5 is 5*1.

Either way you need four 2s and one 5 as prime factors of 80.

We skip the "1" because the definition of "prime" is a number with factors only of itself and one.

Polo · Answer 2

Answer: 2x2x2x2x5=80

Explanation: Because prime factors of a number means prime numbers that can multiply to get another number. Ex. 2 and 3 are both prime numbers, and 2x3=6, so the prime factorization of 6 is 2x3.
