Given numbers are 458, 506, 880, 645

The list of prime factors of all numbers are

Prime factors of 458 are 2 x 229

Prime factors of 506 are 2 x 11 x 23

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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 458, 506, 880, 645

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

Apply this formula for all numbers.

Step1:

LCM(458, 506) = 115874

GCD(458, 506) = ( 458 x 506 ) / 115874

= 458 / 506

= 458

Step2:

LCM(2, 880) = 880

GCD(2, 880) = ( 2 x 880 ) / 880

= 2 / 880

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 458, 506, 880, 645 is 1
