Given numbers are 640, 435, 969

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

Apply this formula for all numbers.

Step1:

LCM(640, 435) = 55680

GCD(640, 435) = ( 640 x 435 ) / 55680

= 640 / 435

= 640

Step2:

LCM(5, 969) = 4845

GCD(5, 969) = ( 5 x 969 ) / 4845

= 5 / 969

= 5

So, Greatest Common Divisor of 640, 435, 969 is 1
