Given numbers are 756, 615, 32, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 615) = 154980
GCD(756, 615) = ( 756 x 615 ) / 154980
= 756 / 615
= 756
Step2:
LCM(3, 32) = 96
GCD(3, 32) = ( 3 x 32 ) / 96
= 3 / 32
= 3
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 756, 615, 32, 391 is 1
