Therefore, GCD of numbers 685, 135, 44, 970 is 1

Given Input Data is 685, 135, 44, 970

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

Prime Factorization of 685 is 5 x 137

Prime Factorization of 135 is 3 x 3 x 3 x 5

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 970 is 2 x 5 x 97

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(685, 135) = 18495

GCD(685, 135) = ( 685 x 135 ) / 18495

GCD(685, 135) = 92475 / 18495

GCD(685, 135) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 44

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

LCM(5, 44) = 220

GCD(5, 44) = ( 5 x 44 ) / 220

GCD(5, 44) = 220 / 220

GCD(5, 44) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 970

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

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

GCD(1, 970) = 970 / 970

GCD(1, 970) = 1

GCD of 685, 135, 44, 970 is 1
