GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 822) = 211254
GCD(771, 822) = ( 771 x 822 ) / 211254
= 771 / 822
= 771
Step2:
LCM(3, 615) = 615
GCD(3, 615) = ( 3 x 615 ) / 615
= 3 / 615
= 3
Step3:
LCM(3, 717) = 717
GCD(3, 717) = ( 3 x 717 ) / 717
= 3 / 717
= 3
So, Greatest Common Divisor of 771, 822, 615, 717 is 3
