Given numbers are 280, 257, 430, 552

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 257 are 257

Prime factors of 430 are 2 x 5 x 43

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

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

Given numbers are 280, 257, 430, 552

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

Apply this formula for all numbers.

Step1:

LCM(280, 257) = 71960

GCD(280, 257) = ( 280 x 257 ) / 71960

= 280 / 257

= 280

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

Step3:

LCM(1, 552) = 552

GCD(1, 552) = ( 1 x 552 ) / 552

= 1 / 552

= 1

So, Greatest Common Divisor of 280, 257, 430, 552 is 1
