Given numbers are 238, 638, 766, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 638) = 75922
GCD(238, 638) = ( 238 x 638 ) / 75922
= 238 / 638
= 238
Step2:
LCM(2, 766) = 766
GCD(2, 766) = ( 2 x 766 ) / 766
= 2 / 766
= 2
Step3:
LCM(2, 657) = 1314
GCD(2, 657) = ( 2 x 657 ) / 1314
= 2 / 657
= 2
So, Greatest Common Divisor of 238, 638, 766, 657 is 1
