Given numbers are 861, 724, 454

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

Apply this formula for all numbers.

Step1:

LCM(861, 724) = 623364

GCD(861, 724) = ( 861 x 724 ) / 623364

= 861 / 724

= 861

Step2:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 861, 724, 454 is 1
