Given numbers are 423, 623, 354, 165

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 623 are 7 x 89

Prime factors of 354 are 2 x 3 x 59

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 423, 623, 354, 165

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

Apply this formula for all numbers.

Step1:

LCM(423, 623) = 263529

GCD(423, 623) = ( 423 x 623 ) / 263529

= 423 / 623

= 423

Step2:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 423, 623, 354, 165 is 1
