Given numbers are 408, 688, 266, 668

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(408, 688) = 35088

GCD(408, 688) = ( 408 x 688 ) / 35088

= 408 / 688

= 408

Step2:

LCM(8, 266) = 1064

GCD(8, 266) = ( 8 x 266 ) / 1064

= 8 / 266

= 8

Step3:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

So, Greatest Common Divisor of 408, 688, 266, 668 is 2
