(口)

Answer 1

Answer:

5(8+13)

Step-by-step explanation:

GCF of 40 and 65 is 5. Divide both by 5 and you get 8 and 13. a=gcf, b=40, c=65

Answer 2

Answer:

5(8+13)

Step-by-step explanation:

Use prime factorization (split 40 and 65 into prime numbers)

40: 2*2*2*5

65: 5*13

The only common number between these is 5, so 5 is the gcf

Then divide both numbers by 5

40/5 = 8

65/5 = 13

so the answer is 5(8 + 13)
