GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(717, 987) = 235893
GCD(717, 987) = ( 717 x 987 ) / 235893
= 717 / 987
= 717
Step2:
LCM(3, 685) = 2055
GCD(3, 685) = ( 3 x 685 ) / 2055
= 3 / 685
= 3
Step3:
LCM(1, 938) = 938
GCD(1, 938) = ( 1 x 938 ) / 938
= 1 / 938
= 1
So, Greatest Common Divisor of 717, 987, 685, 938 is 1
