Given numbers are 861, 538, 413

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

Apply this formula for all numbers.

Step1:

LCM(861, 538) = 463218

GCD(861, 538) = ( 861 x 538 ) / 463218

= 861 / 538

= 861

Step2:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

So, Greatest Common Divisor of 861, 538, 413 is 1
