Given numbers are 409, 428, 504, 685

The list of prime factors of all numbers are

Prime factors of 409 are 409

Prime factors of 428 are 2 x 2 x 107

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 685 are 5 x 137

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

Given numbers are 409, 428, 504, 685

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

Apply this formula for all numbers.

Step1:

LCM(409, 428) = 175052

GCD(409, 428) = ( 409 x 428 ) / 175052

= 409 / 428

= 409

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 409, 428, 504, 685 is 1
