Given numbers are 985, 676, 980, 842

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 676 are 2 x 2 x 13 x 13

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

Prime factors of 842 are 2 x 421

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

Given numbers are 985, 676, 980, 842

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

Apply this formula for all numbers.

Step1:

LCM(985, 676) = 665860

GCD(985, 676) = ( 985 x 676 ) / 665860

= 985 / 676

= 985

Step2:

LCM(1, 980) = 980

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

= 1 / 980

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 985, 676, 980, 842 is 1
