Given numbers are 473, 556, 820, 768

The list of prime factors of all numbers are

Prime factors of 473 are 11 x 43

Prime factors of 556 are 2 x 2 x 139

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 473, 556, 820, 768

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

Apply this formula for all numbers.

Step1:

LCM(473, 556) = 262988

GCD(473, 556) = ( 473 x 556 ) / 262988

= 473 / 556

= 473

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 473, 556, 820, 768 is 1
