Given numbers are 645, 522, 615, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 522) = 112230
GCD(645, 522) = ( 645 x 522 ) / 112230
= 645 / 522
= 645
Step2:
LCM(3, 615) = 615
GCD(3, 615) = ( 3 x 615 ) / 615
= 3 / 615
= 3
Step3:
LCM(3, 306) = 306
GCD(3, 306) = ( 3 x 306 ) / 306
= 3 / 306
= 3
So, Greatest Common Divisor of 645, 522, 615, 306 is 3
