Given numbers are 406, 254, 789, 474

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 254 are 2 x 127

Prime factors of 789 are 3 x 263

Prime factors of 474 are 2 x 3 x 79

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

Given numbers are 406, 254, 789, 474

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

Apply this formula for all numbers.

Step1:

LCM(406, 254) = 51562

GCD(406, 254) = ( 406 x 254 ) / 51562

= 406 / 254

= 406

Step2:

LCM(2, 789) = 1578

GCD(2, 789) = ( 2 x 789 ) / 1578

= 2 / 789

= 2

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 406, 254, 789, 474 is 1
