Given numbers are 780, 656, 189, 939

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

Apply this formula for all numbers.

Step1:

LCM(780, 656) = 127920

GCD(780, 656) = ( 780 x 656 ) / 127920

= 780 / 656

= 780

Step2:

LCM(4, 189) = 756

GCD(4, 189) = ( 4 x 189 ) / 756

= 4 / 189

= 4

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 780, 656, 189, 939 is 1
