Given numbers are 865, 820, 854

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 854 are 2 x 7 x 61

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

Given numbers are 865, 820, 854

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

Apply this formula for all numbers.

Step1:

LCM(865, 820) = 141860

GCD(865, 820) = ( 865 x 820 ) / 141860

= 865 / 820

= 865

Step2:

LCM(5, 854) = 4270

GCD(5, 854) = ( 5 x 854 ) / 4270

= 5 / 854

= 5

So, Greatest Common Divisor of 865, 820, 854 is 1
