Given numbers are 317, 645, 531, 195
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(317, 645) = 204465
GCD(317, 645) = ( 317 x 645 ) / 204465
= 317 / 645
= 317
Step2:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
Step3:
LCM(1, 195) = 195
GCD(1, 195) = ( 1 x 195 ) / 195
= 1 / 195
= 1
So, Greatest Common Divisor of 317, 645, 531, 195 is 1
