Given numbers are 406, 620, 862, 865

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 862 are 2 x 431

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 406, 620, 862, 865

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

Apply this formula for all numbers.

Step1:

LCM(406, 620) = 125860

GCD(406, 620) = ( 406 x 620 ) / 125860

= 406 / 620

= 406

Step2:

LCM(2, 862) = 862

GCD(2, 862) = ( 2 x 862 ) / 862

= 2 / 862

= 2

Step3:

LCM(2, 865) = 1730

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

= 2 / 865

= 2

So, Greatest Common Divisor of 406, 620, 862, 865 is 1
