Given numbers are 225, 345, 689, 161

The list of prime factors of all numbers are

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 345 are 3 x 5 x 23

Prime factors of 689 are 13 x 53

Prime factors of 161 are 7 x 23

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

Given numbers are 225, 345, 689, 161

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

Apply this formula for all numbers.

Step1:

LCM(225, 345) = 5175

GCD(225, 345) = ( 225 x 345 ) / 5175

= 225 / 345

= 225

Step2:

LCM(15, 689) = 10335

GCD(15, 689) = ( 15 x 689 ) / 10335

= 15 / 689

= 15

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 225, 345, 689, 161 is 1
