Therefore, GCD of numbers 781, 572, 10, 551 is 1

Given Input Data is 781, 572, 10, 551

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 572 is 2 x 2 x 11 x 13

Prime Factorization of 10 is 2 x 5

Prime Factorization of 551 is 19 x 29

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(781, 572) = 40612

GCD(781, 572) = ( 781 x 572 ) / 40612

GCD(781, 572) = 446732 / 40612

GCD(781, 572) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 10

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

LCM(11, 10) = 110

GCD(11, 10) = ( 11 x 10 ) / 110

GCD(11, 10) = 110 / 110

GCD(11, 10) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 551

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

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

GCD(1, 551) = 551 / 551

GCD(1, 551) = 1

GCD of 781, 572, 10, 551 is 1
