Given numbers are 400, 485, 784, 785

The list of prime factors of all numbers are

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

Prime factors of 485 are 5 x 97

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

Prime factors of 785 are 5 x 157

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

Given numbers are 400, 485, 784, 785

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

Apply this formula for all numbers.

Step1:

LCM(400, 485) = 38800

GCD(400, 485) = ( 400 x 485 ) / 38800

= 400 / 485

= 400

Step2:

LCM(5, 784) = 3920

GCD(5, 784) = ( 5 x 784 ) / 3920

= 5 / 784

= 5

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 400, 485, 784, 785 is 1
