Given numbers are 399, 233, 406, 972

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 233 are 233

Prime factors of 406 are 2 x 7 x 29

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 399, 233, 406, 972

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

Apply this formula for all numbers.

Step1:

LCM(399, 233) = 92967

GCD(399, 233) = ( 399 x 233 ) / 92967

= 399 / 233

= 399

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 399, 233, 406, 972 is 1
