Given numbers are 455, 659, 561, 446

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 659 are 659

Prime factors of 561 are 3 x 11 x 17

Prime factors of 446 are 2 x 223

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

Given numbers are 455, 659, 561, 446

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

Apply this formula for all numbers.

Step1:

LCM(455, 659) = 299845

GCD(455, 659) = ( 455 x 659 ) / 299845

= 455 / 659

= 455

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 446) = 446

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

= 1 / 446

= 1

So, Greatest Common Divisor of 455, 659, 561, 446 is 1
