Question

f find the HCF of 24 36 and 90
​

Answer 1

Hcf of 24 and 36

a=bq+r

36=24(1)+12

24=12(2)+0

hcf of 12 and 90

90=12(7)+6

12=6(2)+0

therefore hcf of 24 36 and 90 is 6

Factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24.

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and 36.

Factors of 90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90

Therefore, common factor of 24, 36 and 90 = 1, 2, 3 and 6.

Highest common factor (H.C.F) of 24,36 and 90 = 6.
