Given numbers are 668, 620, 763, 677

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

Apply this formula for all numbers.

Step1:

LCM(668, 620) = 103540

GCD(668, 620) = ( 668 x 620 ) / 103540

= 668 / 620

= 668

Step2:

LCM(4, 763) = 3052

GCD(4, 763) = ( 4 x 763 ) / 3052

= 4 / 763

= 4

Step3:

LCM(1, 677) = 677

GCD(1, 677) = ( 1 x 677 ) / 677

= 1 / 677

= 1

So, Greatest Common Divisor of 668, 620, 763, 677 is 1
