Given numbers are 668, 288, 383, 491

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

Apply this formula for all numbers.

Step1:

LCM(668, 288) = 48096

GCD(668, 288) = ( 668 x 288 ) / 48096

= 668 / 288

= 668

Step2:

LCM(4, 383) = 1532

GCD(4, 383) = ( 4 x 383 ) / 1532

= 4 / 383

= 4

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 668, 288, 383, 491 is 1
