Question

find the H.C.F of 455 and 42​

Answer 1

According to the definition of Euclid's theorem,

a=b×q+r where 0≤r<b.

455=42×10+35

42=35×1+7

35=7×5+0

The HCF of 455 and 42 is 7.

So, option A is correct.

Answer 2

Answer:

Since, the last non-zero remainder that is obtained in the process is 7, this means that the HCF of 455 and 42 is 7.
