Given numbers are 402, 821, 297

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

Apply this formula for all numbers.

Step1:

LCM(402, 821) = 330042

GCD(402, 821) = ( 402 x 821 ) / 330042

= 402 / 821

= 402

Step2:

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

= 1 / 297

= 1

So, Greatest Common Divisor of 402, 821, 297 is 1
