Answer 1

Answer: B. 12 and 64

Step-by-step explanation:

Option A is incorrect because the highest common factor for both numbers would be 38 not 4.

Option B:

Factors of 12 are: 1, 2 , 3, 4, 6, 12

Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.

Highest factor of both is 4 and they both add up to 76 so option B must be correct.
