The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 642 are 2 x 3 x 107

Prime factors of 417 are 3 x 139

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

Given numbers are 985, 516, 642, 417

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

Apply this formula for all numbers.

Step1:

LCM(985, 516) = 508260

GCD(985, 516) = ( 985 x 516 ) / 508260

= 985 / 516

= 985

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 985, 516, 642, 417 is 1
