Given numbers are 837, 102, 980, 257

The list of prime factors of all numbers are

Prime factors of 837 are 3 x 3 x 3 x 31

Prime factors of 102 are 2 x 3 x 17

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

Prime factors of 257 are 257

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

Given numbers are 837, 102, 980, 257

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

Apply this formula for all numbers.

Step1:

LCM(837, 102) = 28458

GCD(837, 102) = ( 837 x 102 ) / 28458

= 837 / 102

= 837

Step2:

LCM(3, 980) = 2940

GCD(3, 980) = ( 3 x 980 ) / 2940

= 3 / 980

= 3

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 837, 102, 980, 257 is 1
