GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 816) = 165648
GCD(406, 816) = ( 406 x 816 ) / 165648
= 406 / 816
= 406
Step2:
LCM(2, 374) = 374
GCD(2, 374) = ( 2 x 374 ) / 374
= 2 / 374
= 2
Step3:
LCM(2, 166) = 166
GCD(2, 166) = ( 2 x 166 ) / 166
= 2 / 166
= 2
So, Greatest Common Divisor of 406, 816, 374, 166 is 2
