GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(634, 918) = 291006
GCD(634, 918) = ( 634 x 918 ) / 291006
= 634 / 918
= 634
Step2:
LCM(2, 421) = 842
GCD(2, 421) = ( 2 x 421 ) / 842
= 2 / 421
= 2
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 634, 918, 421, 720 is 1
