Given numbers are 834, 156, 687, 521

The list of prime factors of all numbers are

Prime factors of 834 are 2 x 3 x 139

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 687 are 3 x 229

Prime factors of 521 are 521

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

Given numbers are 834, 156, 687, 521

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

Apply this formula for all numbers.

Step1:

LCM(834, 156) = 21684

GCD(834, 156) = ( 834 x 156 ) / 21684

= 834 / 156

= 834

Step2:

LCM(6, 687) = 1374

GCD(6, 687) = ( 6 x 687 ) / 1374

= 6 / 687

= 6

Step3:

LCM(3, 521) = 1563

GCD(3, 521) = ( 3 x 521 ) / 1563

= 3 / 521

= 3

So, Greatest Common Divisor of 834, 156, 687, 521 is 1
