Given numbers are 406, 768, 422, 783

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 422 are 2 x 211

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 406, 768, 422, 783

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

Apply this formula for all numbers.

Step1:

LCM(406, 768) = 155904

GCD(406, 768) = ( 406 x 768 ) / 155904

= 406 / 768

= 406

Step2:

LCM(2, 422) = 422

GCD(2, 422) = ( 2 x 422 ) / 422

= 2 / 422

= 2

Step3:

LCM(2, 783) = 1566

GCD(2, 783) = ( 2 x 783 ) / 1566

= 2 / 783

= 2

So, Greatest Common Divisor of 406, 768, 422, 783 is 1
