GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 423) = 5922
GCD(126, 423) = ( 126 x 423 ) / 5922
= 126 / 423
= 126
Step2:
LCM(9, 777) = 2331
GCD(9, 777) = ( 9 x 777 ) / 2331
= 9 / 777
= 9
Step3:
LCM(3, 668) = 2004
GCD(3, 668) = ( 3 x 668 ) / 2004
= 3 / 668
= 3
So, Greatest Common Divisor of 126, 423, 777, 668 is 1
