Given numbers are 128, 716, 257, 474

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 716 are 2 x 2 x 179

Prime factors of 257 are 257

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 128, 716, 257, 474

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

Apply this formula for all numbers.

Step1:

LCM(128, 716) = 22912

GCD(128, 716) = ( 128 x 716 ) / 22912

= 128 / 716

= 128

Step2:

LCM(4, 257) = 1028

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

= 4 / 257

= 4

Step3:

LCM(1, 474) = 474

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

= 1 / 474

= 1

So, Greatest Common Divisor of 128, 716, 257, 474 is 1
