Question

HCF of 16 and 40
HCF of 27 and 45
HCF of 42and 30

Answer 1

Answer:

Factors of 16 = 2*2*2*2.

Factors of 40 = 2*2*2*5.

So, HCF = 2*2*2 = 8

Factors of 27 = 3*3*3.

Factors of 45 = 3*3*5.

So, HCF = 3*3 = 9

Factors of 42 = 2*3*7.

Factors of 30 = 2*5*3.

So, HCF = 2*3 = 6

Hope its help u.
