GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 963) = 80892
GCD(756, 963) = ( 756 x 963 ) / 80892
= 756 / 963
= 756
Step2:
LCM(9, 812) = 7308
GCD(9, 812) = ( 9 x 812 ) / 7308
= 9 / 812
= 9
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 756, 963, 812, 309 is 1
