Given numbers are 478, 660, 724, 423

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 724 are 2 x 2 x 181

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 478, 660, 724, 423

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

Apply this formula for all numbers.

Step1:

LCM(478, 660) = 157740

GCD(478, 660) = ( 478 x 660 ) / 157740

= 478 / 660

= 478

Step2:

LCM(2, 724) = 724

GCD(2, 724) = ( 2 x 724 ) / 724

= 2 / 724

= 2

Step3:

LCM(2, 423) = 846

GCD(2, 423) = ( 2 x 423 ) / 846

= 2 / 423

= 2

So, Greatest Common Divisor of 478, 660, 724, 423 is 1
