Given numbers are 257, 612, 828, 280

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

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

Given numbers are 257, 612, 828, 280

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

Apply this formula for all numbers.

Step1:

LCM(257, 612) = 157284

GCD(257, 612) = ( 257 x 612 ) / 157284

= 257 / 612

= 257

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 257, 612, 828, 280 is 1
