Given numbers are 173, 345, 215, 406

The list of prime factors of all numbers are

Prime factors of 173 are 173

Prime factors of 345 are 3 x 5 x 23

Prime factors of 215 are 5 x 43

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 173, 345, 215, 406

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

Apply this formula for all numbers.

Step1:

LCM(173, 345) = 59685

GCD(173, 345) = ( 173 x 345 ) / 59685

= 173 / 345

= 173

Step2:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

Step3:

LCM(1, 406) = 406

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

= 1 / 406

= 1

So, Greatest Common Divisor of 173, 345, 215, 406 is 1
