Given Input Data is 970, 105, 168, 100

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

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 105 is 3 x 5 x 7

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 100 is 2 x 2 x 5 x 5

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(970, 105) = 20370

GCD(970, 105) = ( 970 x 105 ) / 20370

GCD(970, 105) = 101850 / 20370

GCD(970, 105) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 168

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

LCM(5, 168) = 840

GCD(5, 168) = ( 5 x 168 ) / 840

GCD(5, 168) = 840 / 840

GCD(5, 168) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 100

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

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

GCD(1, 100) = 100 / 100

GCD(1, 100) = 1

GCD of 970, 105, 168, 100 is 1
