GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 921) = 223803
GCD(729, 921) = ( 729 x 921 ) / 223803
= 729 / 921
= 729
Step2:
LCM(3, 603) = 603
GCD(3, 603) = ( 3 x 603 ) / 603
= 3 / 603
= 3
Step3:
LCM(3, 615) = 615
GCD(3, 615) = ( 3 x 615 ) / 615
= 3 / 615
= 3
So, Greatest Common Divisor of 729, 921, 603, 615 is 3
