Given numbers are 667, 681, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(667, 681) = 454227
GCD(667, 681) = ( 667 x 681 ) / 454227
= 667 / 681
= 667
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 667, 681, 420 is 1
