Given numbers are 429, 325, 640

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

Apply this formula for all numbers.

Step1:

LCM(429, 325) = 10725

GCD(429, 325) = ( 429 x 325 ) / 10725

= 429 / 325

= 429

Step2:

LCM(13, 640) = 8320

GCD(13, 640) = ( 13 x 640 ) / 8320

= 13 / 640

= 13

So, Greatest Common Divisor of 429, 325, 640 is 1
