Given numbers are 642, 893, 406

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

Apply this formula for all numbers.

Step1:

LCM(642, 893) = 573306

GCD(642, 893) = ( 642 x 893 ) / 573306

= 642 / 893

= 642

Step2:

LCM(1, 406) = 406

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

= 1 / 406

= 1

So, Greatest Common Divisor of 642, 893, 406 is 1
