Question

if hcf of 63 and 77 is expressible in the form 63m - 77*4 find m

Answer 1

Answer:

5

Step-by-step explanation:

hcf of 63 and 77

63 = 3 * 3 * 7

77 = 7 * 11

HCF = Highest common factor

as 7 is only common in both

HCF of 63 & 77 = 7

HCF = 63m - 77*4

Comparing both

63m - 77*4 = 7

Dividing by 7 both sides

=> 9m  - 11*4 = 1

=> 9m - 44 = 1

=> 9m = 1 + 44

=> 9m = 45

Dividing by 9 both sides

=> m = 5
