Question

The HCF of 70,126, 196. Explain in method

Answer 1

Answer:

Ans. H.C.F. stands for Highest Common Factor.

It is the number which is common in all the given numbers.

So, we will first find the factors of 70, 126 and 196.

70=2×5×7

126=2×3×3×7

196=2×2×7×7

So, which are the numbers which are common in the three numbers?

Well, those are 1 and 2 and 7.

We see that 5 is a factor of 70 only(not of 126 and 196), also 3 is a factor of just 126(not of 70 and 196). But 1, 2 and 7 are the common factors.

Hence, the H.C.F. of 70, 126 and 196 is

1×2×7=14
