Given numbers are 985, 320, 121, 684

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 121 are 11 x 11

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 985, 320, 121, 684

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

Apply this formula for all numbers.

Step1:

LCM(985, 320) = 63040

GCD(985, 320) = ( 985 x 320 ) / 63040

= 985 / 320

= 985

Step2:

LCM(5, 121) = 605

GCD(5, 121) = ( 5 x 121 ) / 605

= 5 / 121

= 5

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 985, 320, 121, 684 is 1
