Given numbers are 774, 344, 646, 280

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

Apply this formula for all numbers.

Step1:

LCM(774, 344) = 3096

GCD(774, 344) = ( 774 x 344 ) / 3096

= 774 / 344

= 774

Step2:

LCM(86, 646) = 27778

GCD(86, 646) = ( 86 x 646 ) / 27778

= 86 / 646

= 86

Step3:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

So, Greatest Common Divisor of 774, 344, 646, 280 is 2
