Given numbers are 756, 936, 638, 623
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 936) = 19656
GCD(756, 936) = ( 756 x 936 ) / 19656
= 756 / 936
= 756
Step2:
LCM(36, 638) = 11484
GCD(36, 638) = ( 36 x 638 ) / 11484
= 36 / 638
= 36
Step3:
LCM(2, 623) = 1246
GCD(2, 623) = ( 2 x 623 ) / 1246
= 2 / 623
= 2
So, Greatest Common Divisor of 756, 936, 638, 623 is 1
