Therefore, GCD of numbers 650, 685, 718, 647 is 1

Given Input Data is 650, 685, 718, 647

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

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 685 is 5 x 137

Prime Factorization of 718 is 2 x 359

Prime Factorization of 647 is 647

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(650, 685) = 89050

GCD(650, 685) = ( 650 x 685 ) / 89050

GCD(650, 685) = 445250 / 89050

GCD(650, 685) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 718

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

LCM(5, 718) = 3590

GCD(5, 718) = ( 5 x 718 ) / 3590

GCD(5, 718) = 3590 / 3590

GCD(5, 718) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 647

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

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

GCD(1, 647) = 647 / 647

GCD(1, 647) = 1

GCD of 650, 685, 718, 647 is 1
