Given numbers are 423, 777, 470, 480

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 777 are 3 x 7 x 37

Prime factors of 470 are 2 x 5 x 47

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

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

Given numbers are 423, 777, 470, 480

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

Apply this formula for all numbers.

Step1:

LCM(423, 777) = 109557

GCD(423, 777) = ( 423 x 777 ) / 109557

= 423 / 777

= 423

Step2:

LCM(3, 470) = 1410

GCD(3, 470) = ( 3 x 470 ) / 1410

= 3 / 470

= 3

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 423, 777, 470, 480 is 1
