Given numbers are 398, 335, 170, 623

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 335 are 5 x 67

Prime factors of 170 are 2 x 5 x 17

Prime factors of 623 are 7 x 89

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

Given numbers are 398, 335, 170, 623

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

Apply this formula for all numbers.

Step1:

LCM(398, 335) = 133330

GCD(398, 335) = ( 398 x 335 ) / 133330

= 398 / 335

= 398

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 398, 335, 170, 623 is 1
