Question

Using the division method, find the H.C.F. of the following :

(i) 16 and 24

(ii) 18 and 30

(iii) 7, 14 and 24

(iv) 70,80,120 and 150

(v) 32, 56 and 46

Answer 1

(i) 16 and 24

since last division is 8

so, H.C.F of 16 and 24 = 8

(ii) 18 and 30

since last division is 6

so, H.C.F of 18 and 30 = 6

(iii) 7, 14 and 24

since last division is 1

so, H.C.F of 7,14 and 24 = 1

(iv) 70,80,120 and 150

since last division is 10

so, H.C.F of 70, 80,120 and 159 = 10

(v) 32, 56 and 46

since last division is  2

so, H.C.F of 32,56 and 46 = 2
