Given numbers are 821, 358, 320

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

Apply this formula for all numbers.

Step1:

LCM(821, 358) = 293918

GCD(821, 358) = ( 821 x 358 ) / 293918

= 821 / 358

= 821

Step2:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 821, 358, 320 is 1
