Given numbers are 648, 560, 515, 284

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 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 515 are 5 x 103

Prime factors of 284 are 2 x 2 x 71

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

Given numbers are 648, 560, 515, 284

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

Apply this formula for all numbers.

Step1:

LCM(648, 560) = 45360

GCD(648, 560) = ( 648 x 560 ) / 45360

= 648 / 560

= 648

Step2:

LCM(8, 515) = 4120

GCD(8, 515) = ( 8 x 515 ) / 4120

= 8 / 515

= 8

Step3:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

So, Greatest Common Divisor of 648, 560, 515, 284 is 1
