Given numbers are 785, 609, 400, 865

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 609 are 3 x 7 x 29

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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 785, 609, 400, 865

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

Apply this formula for all numbers.

Step1:

LCM(785, 609) = 478065

GCD(785, 609) = ( 785 x 609 ) / 478065

= 785 / 609

= 785

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 785, 609, 400, 865 is 1
