Given numbers are 393, 828, 412, 720

The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

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

Prime factors of 412 are 2 x 2 x 103

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 393, 828, 412, 720

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

Apply this formula for all numbers.

Step1:

LCM(393, 828) = 108468

GCD(393, 828) = ( 393 x 828 ) / 108468

= 393 / 828

= 393

Step2:

LCM(3, 412) = 1236

GCD(3, 412) = ( 3 x 412 ) / 1236

= 3 / 412

= 3

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 393, 828, 412, 720 is 1
