Given numbers are 774, 777, 737, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(774, 777) = 200466
GCD(774, 777) = ( 774 x 777 ) / 200466
= 774 / 777
= 774
Step2:
LCM(3, 737) = 2211
GCD(3, 737) = ( 3 x 737 ) / 2211
= 3 / 737
= 3
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 774, 777, 737, 420 is 1
