Given numbers are 668, 544, 771, 687

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

Apply this formula for all numbers.

Step1:

LCM(668, 544) = 90848

GCD(668, 544) = ( 668 x 544 ) / 90848

= 668 / 544

= 668

Step2:

LCM(4, 771) = 3084

GCD(4, 771) = ( 4 x 771 ) / 3084

= 4 / 771

= 4

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 668, 544, 771, 687 is 1
