Given numbers are 455, 583, 122, 645

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 583 are 11 x 53

Prime factors of 122 are 2 x 61

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 455, 583, 122, 645

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

Apply this formula for all numbers.

Step1:

LCM(455, 583) = 265265

GCD(455, 583) = ( 455 x 583 ) / 265265

= 455 / 583

= 455

Step2:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 455, 583, 122, 645 is 1
