GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(624, 729) = 151632
GCD(624, 729) = ( 624 x 729 ) / 151632
= 624 / 729
= 624
Step2:
LCM(3, 515) = 1545
GCD(3, 515) = ( 3 x 515 ) / 1545
= 3 / 515
= 3
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 624, 729, 515, 291 is 1
