Given numbers are 861, 303, 251, 839

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

Apply this formula for all numbers.

Step1:

LCM(861, 303) = 86961

GCD(861, 303) = ( 861 x 303 ) / 86961

= 861 / 303

= 861

Step2:

LCM(3, 251) = 753

GCD(3, 251) = ( 3 x 251 ) / 753

= 3 / 251

= 3

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 861, 303, 251, 839 is 1
