Given numbers are 328, 521, 638

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

Apply this formula for all numbers.

Step1:

LCM(328, 521) = 170888

GCD(328, 521) = ( 328 x 521 ) / 170888

= 328 / 521

= 328

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 328, 521, 638 is 1
