GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 591) = 78603
GCD(399, 591) = ( 399 x 591 ) / 78603
= 399 / 591
= 399
Step2:
LCM(3, 156) = 156
GCD(3, 156) = ( 3 x 156 ) / 156
= 3 / 156
= 3
Step3:
LCM(3, 668) = 2004
GCD(3, 668) = ( 3 x 668 ) / 2004
= 3 / 668
= 3
So, Greatest Common Divisor of 399, 591, 156, 668 is 1
