Given numbers are 684, 140, 980, 835

The list of prime factors of all numbers are

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

Prime factors of 140 are 2 x 2 x 5 x 7

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

Prime factors of 835 are 5 x 167

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

Given numbers are 684, 140, 980, 835

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

Apply this formula for all numbers.

Step1:

LCM(684, 140) = 23940

GCD(684, 140) = ( 684 x 140 ) / 23940

= 684 / 140

= 684

Step2:

LCM(4, 980) = 980

GCD(4, 980) = ( 4 x 980 ) / 980

= 4 / 980

= 4

Step3:

LCM(4, 835) = 3340

GCD(4, 835) = ( 4 x 835 ) / 3340

= 4 / 835

= 4

So, Greatest Common Divisor of 684, 140, 980, 835 is 1
