GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(888, 126) = 18648
GCD(888, 126) = ( 888 x 126 ) / 18648
= 888 / 126
= 888
Step2:
LCM(6, 999) = 1998
GCD(6, 999) = ( 6 x 999 ) / 1998
= 6 / 999
= 6
Step3:
LCM(3, 420) = 420
GCD(3, 420) = ( 3 x 420 ) / 420
= 3 / 420
= 3
So, Greatest Common Divisor of 888, 126, 999, 420 is 3
