Given numbers are 756, 123, 230, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 123) = 30996
GCD(756, 123) = ( 756 x 123 ) / 30996
= 756 / 123
= 756
Step2:
LCM(3, 230) = 690
GCD(3, 230) = ( 3 x 230 ) / 690
= 3 / 230
= 3
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 756, 123, 230, 640 is 1
