Given numbers are 254, 784, 858, 865

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 865 are 5 x 173

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

Given numbers are 254, 784, 858, 865

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

Apply this formula for all numbers.

Step1:

LCM(254, 784) = 99568

GCD(254, 784) = ( 254 x 784 ) / 99568

= 254 / 784

= 254

Step2:

LCM(2, 858) = 858

GCD(2, 858) = ( 2 x 858 ) / 858

= 2 / 858

= 2

Step3:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

So, Greatest Common Divisor of 254, 784, 858, 865 is 1
