Given numbers are 729, 647, 417, 724
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 647) = 471663
GCD(729, 647) = ( 729 x 647 ) / 471663
= 729 / 647
= 729
Step2:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
Step3:
LCM(1, 724) = 724
GCD(1, 724) = ( 1 x 724 ) / 724
= 1 / 724
= 1
So, Greatest Common Divisor of 729, 647, 417, 724 is 1
