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

Given numbers are 136, 828, 686, 521

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

Apply this formula for all numbers.

Step1:

LCM(136, 828) = 28152

GCD(136, 828) = ( 136 x 828 ) / 28152

= 136 / 828

= 136

Step2:

LCM(4, 686) = 1372

GCD(4, 686) = ( 4 x 686 ) / 1372

= 4 / 686

= 4

Step3:

LCM(2, 521) = 1042

GCD(2, 521) = ( 2 x 521 ) / 1042

= 2 / 521

= 2

So, Greatest Common Divisor of 136, 828, 686, 521 is 1
