Given numbers are 981, 960, 257, 498

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 257 are 257

Prime factors of 498 are 2 x 3 x 83

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

Given numbers are 981, 960, 257, 498

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

Apply this formula for all numbers.

Step1:

LCM(981, 960) = 313920

GCD(981, 960) = ( 981 x 960 ) / 313920

= 981 / 960

= 981

Step2:

LCM(3, 257) = 771

GCD(3, 257) = ( 3 x 257 ) / 771

= 3 / 257

= 3

Step3:

LCM(1, 498) = 498

GCD(1, 498) = ( 1 x 498 ) / 498

= 1 / 498

= 1

So, Greatest Common Divisor of 981, 960, 257, 498 is 1
