GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(317, 687) = 217779
GCD(317, 687) = ( 317 x 687 ) / 217779
= 317 / 687
= 317
Step2:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
Step3:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
So, Greatest Common Divisor of 317, 687, 109, 256 is 1
