GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 170) = 56610
GCD(666, 170) = ( 666 x 170 ) / 56610
= 666 / 170
= 666
Step2:
LCM(2, 644) = 644
GCD(2, 644) = ( 2 x 644 ) / 644
= 2 / 644
= 2
Step3:
LCM(2, 246) = 246
GCD(2, 246) = ( 2 x 246 ) / 246
= 2 / 246
= 2
So, Greatest Common Divisor of 666, 170, 644, 246 is 2
