Given numbers are 861, 427, 203, 930

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 427 are 7 x 61

Prime factors of 203 are 7 x 29

Prime factors of 930 are 2 x 3 x 5 x 31

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 861, 427, 203, 930

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

Apply this formula for all numbers.

Step1:

LCM(861, 427) = 52521

GCD(861, 427) = ( 861 x 427 ) / 52521

= 861 / 427

= 861

Step2:

LCM(7, 203) = 203

GCD(7, 203) = ( 7 x 203 ) / 203

= 7 / 203

= 7

Step3:

LCM(7, 930) = 6510

GCD(7, 930) = ( 7 x 930 ) / 6510

= 7 / 930

= 7

So, Greatest Common Divisor of 861, 427, 203, 930 is 1
