Given numbers are 317, 640, 225, 581
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(317, 640) = 202880
GCD(317, 640) = ( 317 x 640 ) / 202880
= 317 / 640
= 317
Step2:
LCM(1, 225) = 225
GCD(1, 225) = ( 1 x 225 ) / 225
= 1 / 225
= 1
Step3:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
So, Greatest Common Divisor of 317, 640, 225, 581 is 1
