Given numbers are 447, 427, 135, 664

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 427 are 7 x 61

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 447, 427, 135, 664

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

Apply this formula for all numbers.

Step1:

LCM(447, 427) = 190869

GCD(447, 427) = ( 447 x 427 ) / 190869

= 447 / 427

= 447

Step2:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 447, 427, 135, 664 is 1
