Given numbers are 238, 638, 650, 238
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, 650) = 650
GCD(2, 650) = ( 2 x 650 ) / 650
= 2 / 650
= 2
Step3:
LCM(2, 238) = 238
GCD(2, 238) = ( 2 x 238 ) / 238
= 2 / 238
= 2
So, Greatest Common Divisor of 238, 638, 650, 238 is 2
