Given numbers are 255, 749, 446, 455

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 749 are 7 x 107

Prime factors of 446 are 2 x 223

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 255, 749, 446, 455

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

Apply this formula for all numbers.

Step1:

LCM(255, 749) = 190995

GCD(255, 749) = ( 255 x 749 ) / 190995

= 255 / 749

= 255

Step2:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 255, 749, 446, 455 is 1
