Given numbers are 939, 620, 763, 690

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

Apply this formula for all numbers.

Step1:

LCM(939, 620) = 582180

GCD(939, 620) = ( 939 x 620 ) / 582180

= 939 / 620

= 939

Step2:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 939, 620, 763, 690 is 1
