common factor
A common factor is a number that divides two or more numbers exactly without leaving a remainder
A common factor is a number that divides two or more numbers exactly without leaving a remainder.
For example, let’s consider the numbers 6 and 12. The factors of 6 are 1, 2, 3, and 6. The factors of 12 are 1, 2, 3, 4, 6, and 12. As you can see, 1, 2, 3, and 6 are the common factors of 6 and 12, because they both divide evenly into both numbers.
To find common factors, it is helpful to list the factors of each number and compare them. The factors can be determined by finding all the numbers that divide into the given number without leaving a remainder.
For larger numbers, you can use some strategies to determine the common factors more efficiently. One method is prime factorization, where you find the prime factors of each number and identify the common ones.
For example, let’s consider the numbers 18, 24, and 36. First, find the prime factors of each number:
18 = 2 x 3 x 3
24 = 2 x 2 x 2 x 3
36 = 2 x 2 x 3 x 3
Now, identify the common prime factors, which are 2 and 3. Multiply these common factors together to find the common factors of the three numbers:
Common factors = 2 x 3 = 6
Therefore, 6 is a common factor of 18, 24, and 36.
Common factors are often used in simplifying fractions or finding the greatest common factor (GCF) of two or more numbers.
