Question

of a=7b what is the HCF of a and b​

Answer 1

Answer: 7 is the HCF of a and b.

Step-by-step explanation:

Given a = 7b,

We can also write it as a = 7b + 0

By Euclid’s Division Lemma, a = bq + r

When the Remainder comes to be zero, the divisor is the HCF of the two numbers.

In this case, 7 is the divisor and remainder = 0, Hence, 7 is the HCF of a and b.
