Given numbers are 861, 857, 864, 194

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 857 are 857

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 194 are 2 x 97

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

Given numbers are 861, 857, 864, 194

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

Apply this formula for all numbers.

Step1:

LCM(861, 857) = 737877

GCD(861, 857) = ( 861 x 857 ) / 737877

= 861 / 857

= 861

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 861, 857, 864, 194 is 1
