Given numbers are 648, 288, 127, 815

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 127 are 127

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 648, 288, 127, 815

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

Apply this formula for all numbers.

Step1:

LCM(648, 288) = 2592

GCD(648, 288) = ( 648 x 288 ) / 2592

= 648 / 288

= 648

Step2:

LCM(72, 127) = 9144

GCD(72, 127) = ( 72 x 127 ) / 9144

= 72 / 127

= 72

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 648, 288, 127, 815 is 1
