Given numbers are 668, 138, 356, 889

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

Apply this formula for all numbers.

Step1:

LCM(668, 138) = 46092

GCD(668, 138) = ( 668 x 138 ) / 46092

= 668 / 138

= 668

Step2:

LCM(2, 356) = 356

GCD(2, 356) = ( 2 x 356 ) / 356

= 2 / 356

= 2

Step3:

LCM(2, 889) = 1778

GCD(2, 889) = ( 2 x 889 ) / 1778

= 2 / 889

= 2

So, Greatest Common Divisor of 668, 138, 356, 889 is 1
