Therefore, GCD of numbers 980, 368, 88, 261 is 1

Given Input Data is 980, 368, 88, 261

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

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 368 is 2 x 2 x 2 x 2 x 23

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 261 is 3 x 3 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(980, 368) = 90160

GCD(980, 368) = ( 980 x 368 ) / 90160

GCD(980, 368) = 360640 / 90160

GCD(980, 368) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 88

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

LCM(4, 88) = 88

GCD(4, 88) = ( 4 x 88 ) / 88

GCD(4, 88) = 352 / 88

GCD(4, 88) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 261

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

LCM(4, 261) = 1044

GCD(4, 261) = ( 4 x 261 ) / 1044

GCD(4, 261) = 1044 / 1044

GCD(4, 261) = 1

GCD of 980, 368, 88, 261 is 1
