Therefore, GCD of numbers 284, 676, 63, 688 is 1

Given Input Data is 284, 676, 63, 688

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 284 is 2 x 2 x 71

Prime Factorization of 676 is 2 x 2 x 13 x 13

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(284, 676) = 47996

GCD(284, 676) = ( 284 x 676 ) / 47996

GCD(284, 676) = 191984 / 47996

GCD(284, 676) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 63

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(4, 63) = 252

GCD(4, 63) = ( 4 x 63 ) / 252

GCD(4, 63) = 252 / 252

GCD(4, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 688

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

GCD(1, 688) = 688 / 688

GCD(1, 688) = 1

GCD of 284, 676, 63, 688 is 1
