Given numbers are 520, 648, 168, 393

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 393 are 3 x 131

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

Given numbers are 520, 648, 168, 393

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

Apply this formula for all numbers.

Step1:

LCM(520, 648) = 42120

GCD(520, 648) = ( 520 x 648 ) / 42120

= 520 / 648

= 520

Step2:

LCM(8, 168) = 168

GCD(8, 168) = ( 8 x 168 ) / 168

= 8 / 168

= 8

Step3:

LCM(8, 393) = 3144

GCD(8, 393) = ( 8 x 393 ) / 3144

= 8 / 393

= 8

So, Greatest Common Divisor of 520, 648, 168, 393 is 1
