Given numbers are 408, 428, 257, 112

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 428 are 2 x 2 x 107

Prime factors of 257 are 257

Prime factors of 112 are 2 x 2 x 2 x 2 x 7

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

Given numbers are 408, 428, 257, 112

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

Apply this formula for all numbers.

Step1:

LCM(408, 428) = 43656

GCD(408, 428) = ( 408 x 428 ) / 43656

= 408 / 428

= 408

Step2:

LCM(4, 257) = 1028

GCD(4, 257) = ( 4 x 257 ) / 1028

= 4 / 257

= 4

Step3:

LCM(1, 112) = 112

GCD(1, 112) = ( 1 x 112 ) / 112

= 1 / 112

= 1

So, Greatest Common Divisor of 408, 428, 257, 112 is 1
