GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 400) = 66800
GCD(668, 400) = ( 668 x 400 ) / 66800
= 668 / 400
= 668
Step2:
LCM(4, 816) = 816
GCD(4, 816) = ( 4 x 816 ) / 816
= 4 / 816
= 4
Step3:
LCM(4, 854) = 1708
GCD(4, 854) = ( 4 x 854 ) / 1708
= 4 / 854
= 4
So, Greatest Common Divisor of 668, 400, 816, 854 is 2
