Given numbers are 427, 803, 861

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

Apply this formula for all numbers.

Step1:

LCM(427, 803) = 342881

GCD(427, 803) = ( 427 x 803 ) / 342881

= 427 / 803

= 427

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 427, 803, 861 is 1
