10∣2 5∣5 1 10 = 2 ∗ 5 t h e n u mb er 2 i s f a c t or o f 10 b u t n o t m u lt i pl e o f 5
Factors of 10: 1, 10, 2, 5
Multiples of 5: 5, 10, 15, etc.
From this, we see that 5 and 10 are factors of 10 and multiples of 5. Therefore, there are two numbers that are factors of 10 but not 5.
They are: 1 and 2
The numbers that are factors of 10 but not multiples of 5 are 1 and 2. Among these, 2 is specifically a factor that fits the criteria. Therefore, 2 is the answer to the question.
