What is the gcf of 45 and 60 using prime factorization?

45 = 3×3×5

60 = 2×2×3×5

Factors that are common to both products are 3×5.

3×5 = 15 is the GCF of 45 and 60

15

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
