Given numbers are 782, 817, 321

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

Apply this formula for all numbers.

Step1:

LCM(782, 817) = 638894

GCD(782, 817) = ( 782 x 817 ) / 638894

= 782 / 817

= 782

Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 782, 817, 321 is 1
