Given numbers are 985, 178, 102, 980

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 178 are 2 x 89

Prime factors of 102 are 2 x 3 x 17

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

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

Given numbers are 985, 178, 102, 980

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

Apply this formula for all numbers.

Step1:

LCM(985, 178) = 175330

GCD(985, 178) = ( 985 x 178 ) / 175330

= 985 / 178

= 985

Step2:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 985, 178, 102, 980 is 1
