Given numbers are 668, 351, 544, 225

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 225 are 3 x 3 x 5 x 5

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

Given numbers are 668, 351, 544, 225

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

Apply this formula for all numbers.

Step1:

LCM(668, 351) = 234468

GCD(668, 351) = ( 668 x 351 ) / 234468

= 668 / 351

= 668

Step2:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 668, 351, 544, 225 is 1
