Given numbers are 774, 780, 126, 790

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

Apply this formula for all numbers.

Step1:

LCM(774, 780) = 100620

GCD(774, 780) = ( 774 x 780 ) / 100620

= 774 / 780

= 774

Step2:

LCM(6, 126) = 126

GCD(6, 126) = ( 6 x 126 ) / 126

= 6 / 126

= 6

Step3:

LCM(6, 790) = 2370

GCD(6, 790) = ( 6 x 790 ) / 2370

= 6 / 790

= 6

So, Greatest Common Divisor of 774, 780, 126, 790 is 2
