Given numbers are 815, 648, 417, 452

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 417 are 3 x 139

Prime factors of 452 are 2 x 2 x 113

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

Given numbers are 815, 648, 417, 452

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

Apply this formula for all numbers.

Step1:

LCM(815, 648) = 528120

GCD(815, 648) = ( 815 x 648 ) / 528120

= 815 / 648

= 815

Step2:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

Step3:

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

= 1 / 452

= 1

So, Greatest Common Divisor of 815, 648, 417, 452 is 1
