Answer:
The common factors of 4 and 18 are 1 and 2.
The greatest common factor of 4 and 18 is 2.
Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.
Methods:
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 4 are 1, 2, and 4.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The common factors are 1 and 2; the greatest common factor is 2.
The common factors and greatest common factor can also be calculated by identifying the common prime factors and multiplying them together to identify the greatest common factor, and then taking all the factors of it to determine the common factors.
The prime factors of 4 are 2 and 2.
The prime factors of 18 are 2, 3, and 3.
The prime factors in common are a single 2, so the greatest common factor is 2. The factors of 2 are 1 and 2, which are the common factors.
