GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 729) = 158922
GCD(654, 729) = ( 654 x 729 ) / 158922
= 654 / 729
= 654
Step2:
LCM(3, 435) = 435
GCD(3, 435) = ( 3 x 435 ) / 435
= 3 / 435
= 3
Step3:
LCM(3, 987) = 987
GCD(3, 987) = ( 3 x 987 ) / 987
= 3 / 987
= 3
So, Greatest Common Divisor of 654, 729, 435, 987 is 3
