Given numbers are 129, 939, 828, 986

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

Apply this formula for all numbers.

Step1:

LCM(129, 939) = 40377

GCD(129, 939) = ( 129 x 939 ) / 40377

= 129 / 939

= 129

Step2:

LCM(3, 828) = 828

GCD(3, 828) = ( 3 x 828 ) / 828

= 3 / 828

= 3

Step3:

LCM(3, 986) = 2958

GCD(3, 986) = ( 3 x 986 ) / 2958

= 3 / 986

= 3

So, Greatest Common Divisor of 129, 939, 828, 986 is 1
