Given numbers are 456, 255, 455, 622

The list of prime factors of all numbers are

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 255 are 3 x 5 x 17

Prime factors of 455 are 5 x 7 x 13

Prime factors of 622 are 2 x 311

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

Given numbers are 456, 255, 455, 622

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

Apply this formula for all numbers.

Step1:

LCM(456, 255) = 38760

GCD(456, 255) = ( 456 x 255 ) / 38760

= 456 / 255

= 456

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

So, Greatest Common Divisor of 456, 255, 455, 622 is 1
