So the Greatest Common Divisior 631, 570, 965, 742 is 1.

Therefore, GCD of numbers 631, 570, 965, 742 is 1

Given Input Data is 631, 570, 965, 742

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

Prime Factorization of 631 is 631

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 965 is 5 x 193

Prime Factorization of 742 is 2 x 7 x 53

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(631, 570) = 359670

GCD(631, 570) = ( 631 x 570 ) / 359670

GCD(631, 570) = 359670 / 359670

GCD(631, 570) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 965

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

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

GCD(1, 965) = 965 / 965

GCD(1, 965) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 742

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

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

GCD(1, 742) = 742 / 742

GCD(1, 742) = 1

GCD of 631, 570, 965, 742 is 1
