Given numbers are 686, 330, 435, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 330) = 113190
GCD(686, 330) = ( 686 x 330 ) / 113190
= 686 / 330
= 686
Step2:
LCM(2, 435) = 870
GCD(2, 435) = ( 2 x 435 ) / 870
= 2 / 435
= 2
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 686, 330, 435, 657 is 1
