Given numbers are 257, 702, 558, 450

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 257, 702, 558, 450

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

Apply this formula for all numbers.

Step1:

LCM(257, 702) = 180414

GCD(257, 702) = ( 257 x 702 ) / 180414

= 257 / 702

= 257

Step2:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 257, 702, 558, 450 is 1
