Given numbers are 774, 921, 285, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(774, 921) = 237618
GCD(774, 921) = ( 774 x 921 ) / 237618
= 774 / 921
= 774
Step2:
LCM(3, 285) = 285
GCD(3, 285) = ( 3 x 285 ) / 285
= 3 / 285
= 3
Step3:
LCM(3, 836) = 2508
GCD(3, 836) = ( 3 x 836 ) / 2508
= 3 / 836
= 3
So, Greatest Common Divisor of 774, 921, 285, 836 is 1
