Given numbers are 480, 612, 621, 764

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 764 are 2 x 2 x 191

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

Given numbers are 480, 612, 621, 764

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

Apply this formula for all numbers.

Step1:

LCM(480, 612) = 24480

GCD(480, 612) = ( 480 x 612 ) / 24480

= 480 / 612

= 480

Step2:

LCM(12, 621) = 2484

GCD(12, 621) = ( 12 x 621 ) / 2484

= 12 / 621

= 12

Step3:

LCM(3, 764) = 2292

GCD(3, 764) = ( 3 x 764 ) / 2292

= 3 / 764

= 3

So, Greatest Common Divisor of 480, 612, 621, 764 is 1
