Given numbers are 438, 819, 472, 356

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 472 are 2 x 2 x 2 x 59

Prime factors of 356 are 2 x 2 x 89

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

Given numbers are 438, 819, 472, 356

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

Apply this formula for all numbers.

Step1:

LCM(438, 819) = 119574

GCD(438, 819) = ( 438 x 819 ) / 119574

= 438 / 819

= 438

Step2:

LCM(3, 472) = 1416

GCD(3, 472) = ( 3 x 472 ) / 1416

= 3 / 472

= 3

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 438, 819, 472, 356 is 1
