Therefore, GCD of numbers 260, 247, 43, 722 is 1

Given Input Data is 260, 247, 43, 722

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

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 247 is 13 x 19

Prime Factorization of 43 is 43

Prime Factorization of 722 is 2 x 19 x 19

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(260, 247) = 4940

GCD(260, 247) = ( 260 x 247 ) / 4940

GCD(260, 247) = 64220 / 4940

GCD(260, 247) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 43

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

LCM(13, 43) = 559

GCD(13, 43) = ( 13 x 43 ) / 559

GCD(13, 43) = 559 / 559

GCD(13, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 722

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

LCM(1, 722) = 722

GCD(1, 722) = ( 1 x 722 ) / 722

GCD(1, 722) = 722 / 722

GCD(1, 722) = 1

GCD of 260, 247, 43, 722 is 1
