1, 2, 3 and 6
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a common factor of 9 and 12.
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.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a common factor of 9 and 12.
12 14
Since 12 is a factor of 24, all of its factors, prime or otherwise, are common.
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.
The numbers that go into both 12 and 20 are called common factors. To find the common factors of two numbers, you need to identify all the factors of each number and then determine which factors they have in common. The factors of 12 are 1, 2, 3, 4, 6, and 12, while the factors of 20 are 1, 2, 4, 5, 10, and 20. The common factors of 12 and 20 are 1, 2, and 4.
The common factors of 12 and 21 are 1 and 3. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. This means that the greatest common factor is 3. The numbers are 1 and 3
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. When put in a list, the largest of these is known as the greatest common factor, or GCF. Some people refer to this as the highest common factor, or HCF. Calling it the most common factor would be confusing, since people tend to think of "most common" as something that happens frequently.
All numbers have factors. Some factors are prime numbers. These are known as prime factors. Some numbers have some of the same prime factors as other numbers. These are known as common prime factors. 3 is a common prime factor of 12 and 15.
Common factors of both numbers are: 1, 2, 3 and 6
If that's 12, 18 and 24, 1, 2, 3 and 6 are common factors of all three.
