Given numbers are 458, 484, 645, 378

The list of prime factors of all numbers are

Prime factors of 458 are 2 x 229

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 645 are 3 x 5 x 43

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 458, 484, 645, 378

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

Apply this formula for all numbers.

Step1:

LCM(458, 484) = 110836

GCD(458, 484) = ( 458 x 484 ) / 110836

= 458 / 484

= 458

Step2:

LCM(2, 645) = 1290

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

= 2 / 645

= 2

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 458, 484, 645, 378 is 1
