Question

Find the HCF of 70, 140 and 420 by long division method.​

Answer 1

Answer:

HCF of 70 , 140 and 420 is 70

Step-by-step explanation:

by using Euclid division algorithm

70 < 140

140 = 70 ( 2 ) + 0

their HCF is 70

now,

HCF of 70 , 140 : 420

70 < 420

420 = 70 ( 6 ) + 0

so, the HCF of 70 , 140 and 420 is 70
