GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 774) = 54954
GCD(639, 774) = ( 639 x 774 ) / 54954
= 639 / 774
= 639
Step2:
LCM(9, 460) = 4140
GCD(9, 460) = ( 9 x 460 ) / 4140
= 9 / 460
= 9
Step3:
LCM(1, 538) = 538
GCD(1, 538) = ( 1 x 538 ) / 538
= 1 / 538
= 1
So, Greatest Common Divisor of 639, 774, 460, 538 is 1
