Given numbers are 980, 528, 242, 391

The list of prime factors of all numbers are

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 242 are 2 x 11 x 11

Prime factors of 391 are 17 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 980, 528, 242, 391

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(980, 528) = 129360

GCD(980, 528) = ( 980 x 528 ) / 129360

= 980 / 528

= 980

Step2:

LCM(4, 242) = 484

GCD(4, 242) = ( 4 x 242 ) / 484

= 4 / 242

= 4

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 980, 528, 242, 391 is 1
