Given numbers are 638, 315, 865, 229
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 315) = 200970
GCD(638, 315) = ( 638 x 315 ) / 200970
= 638 / 315
= 638
Step2:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
Step3:
LCM(1, 229) = 229
GCD(1, 229) = ( 1 x 229 ) / 229
= 1 / 229
= 1
So, Greatest Common Divisor of 638, 315, 865, 229 is 1
