Given numbers are 447, 374, 864, 815

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 374 are 2 x 11 x 17

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 815 are 5 x 163

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

Given numbers are 447, 374, 864, 815

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

Apply this formula for all numbers.

Step1:

LCM(447, 374) = 167178

GCD(447, 374) = ( 447 x 374 ) / 167178

= 447 / 374

= 447

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 447, 374, 864, 815 is 1
