Given numbers are 393, 177, 638, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 177) = 23187
GCD(393, 177) = ( 393 x 177 ) / 23187
= 393 / 177
= 393
Step2:
LCM(3, 638) = 1914
GCD(3, 638) = ( 3 x 638 ) / 1914
= 3 / 638
= 3
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 393, 177, 638, 634 is 1
