Question

Using repeated subtraction method, find the HCF of the following:
(i) 42 and 70

Answer 1

Step-by-step explanation:

42 and 70.

Let number be m & n.

m > n.

We do m – n & the result of subtraction becomes new 'm'. if m becomes less than n, we do n – m and then assign the result as n. ...

42 and 70 now m = 70, n = 42.

70 – 42 = 28, now m = 42, n = 28.

42 – 28 = 14, now m = 28, n = 14.

28 – 14= 14, now m = 14, n = 14.
