Given numbers are 783, 939, 877, 646

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

Apply this formula for all numbers.

Step1:

LCM(783, 939) = 245079

GCD(783, 939) = ( 783 x 939 ) / 245079

= 783 / 939

= 783

Step2:

LCM(3, 877) = 2631

GCD(3, 877) = ( 3 x 877 ) / 2631

= 3 / 877

= 3

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 783, 939, 877, 646 is 1
