Given numbers are 243, 615, 72, 517
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 615) = 49815
GCD(243, 615) = ( 243 x 615 ) / 49815
= 243 / 615
= 243
Step2:
LCM(3, 72) = 72
GCD(3, 72) = ( 3 x 72 ) / 72
= 3 / 72
= 3
Step3:
LCM(3, 517) = 1551
GCD(3, 517) = ( 3 x 517 ) / 1551
= 3 / 517
= 3
So, Greatest Common Divisor of 243, 615, 72, 517 is 1
