Given numbers are 518, 628, 515, 828

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 628 are 2 x 2 x 157

Prime factors of 515 are 5 x 103

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 518, 628, 515, 828

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

Apply this formula for all numbers.

Step1:

LCM(518, 628) = 162652

GCD(518, 628) = ( 518 x 628 ) / 162652

= 518 / 628

= 518

Step2:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 518, 628, 515, 828 is 1
