All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
Any multiple of 3.
It is 3 that is a common prime factor to both numbers
They are 33 and any of its multiples
There is neither a greatest common factor nor common factors of a single number, such as 3, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 3 are 1 and 3. The prime factor of 3 is 3. Examples: The common factors of 3 and 20 are only 1; the greatest common factor is 1. The common factors of 3 and 81 are 1 and 3; the greatest common factor is 3.
The factor numbers are 3 and -17.
Any number that is a multiple of 3 has 3 as a factor.
There are an infinite number of numbers with 3 as a factor. Any number evenly divisible by 3 has 3 as a factor. That means 6, 9, 12, 15, 18, ..., all have 3 as a factor.
Multiples of 3.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.
No.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
30 has three prime numbers and is a factor of 60.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors because they are factors that the numbers have in common. 3 is a factor of 12. 3 is a factor of 15. 3 is a common factor of 12 and 15.
1, as the three numbers only share 1 as a factor.
3 Is the highest common factor because the last digit of both the numbers are divisible by 3.
