Given numbers are 764, 404, 656, 690

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

Apply this formula for all numbers.

Step1:

LCM(764, 404) = 77164

GCD(764, 404) = ( 764 x 404 ) / 77164

= 764 / 404

= 764

Step2:

LCM(4, 656) = 656

GCD(4, 656) = ( 4 x 656 ) / 656

= 4 / 656

= 4

Step3:

LCM(4, 690) = 1380

GCD(4, 690) = ( 4 x 690 ) / 1380

= 4 / 690

= 4

So, Greatest Common Divisor of 764, 404, 656, 690 is 2
