Given numbers are 861, 188, 803, 684

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 188 are 2 x 2 x 47

Prime factors of 803 are 11 x 73

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 861, 188, 803, 684

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

Apply this formula for all numbers.

Step1:

LCM(861, 188) = 161868

GCD(861, 188) = ( 861 x 188 ) / 161868

= 861 / 188

= 861

Step2:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 861, 188, 803, 684 is 1
