12 and 24
20 and 40 have 4 and 5 as common factors.
12 and 24
20 and 40
1, 2 and 4
These numbers, known as the common factors of 24 and 100, are:1, 2 and 4.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors.
The first two common multiples of the pair of numbers 4 and 6 are: 12, 24.
Since 1, known as the "multiplicative identity", cannot be counted as a factor, there are many pairs of numbers that do not have common factors, such as 2 and 3, 2 and 5, and 3 and 5. There are many pairs of composite (not prime) numbers without common factors, such as 4 and 9. Also, since prime numbers do not have factors, any pair of primes cannot have a common factor, though a pair in which one number is prime may, e.g. 5 and 10.
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors.Common factors are factors that two or more numbers have in common. These are factors that are the same. All integers will have 1 as a common factor. Some integers will have additional common factors. For example, 4 and 6 have as their common factors 1 and 2.Numbers that evenly divide one or more numbersEx: 2 is a common factor for the numbers 4 and 6
what are the common factors of 4 20 and 24
There is neither a greatest common factor nor common factors of a single number, such as 4, 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 4 are 1, 2, and 4. The prime factors of 4 are 2 and 2. Examples: The common factors of 4 and 36 are 1, 2, and 4; the greatest common factor is 4. The common factors of 4 and 54 are 1 and 2; the greatest common factor is 2.
The common factors of the three numbers are 1, 2, and 4.
