Given numbers are 921, 817, 406

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

Apply this formula for all numbers.

Step1:

LCM(921, 817) = 752457

GCD(921, 817) = ( 921 x 817 ) / 752457

= 921 / 817

= 921

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 921, 817, 406 is 1
