Given numbers are 517, 156, 685, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(517, 156) = 80652
GCD(517, 156) = ( 517 x 156 ) / 80652
= 517 / 156
= 517
Step2:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 517, 156, 685, 231 is 1
