What is the Greatest Common Factor of 4k, 18k^4, and 12?

The greatest common factor (GCF) is a fundamental concept in mathematics that plays a crucial role in algebra, geometry, and other branches of mathematics. It is essential to understand the GCF to solve various mathematical problems, including those involving polynomials, fractions, and decimals. In this article, we will explore the concept of the GCF and determine the greatest common factor of 4k, 18k^4, and 12.

Understanding the Greatest Common Factor

The greatest common factor (GCF) of a set of numbers is the largest positive integer that divides each of the numbers in the set without leaving a remainder. In other words, it is the largest number that can be factored out of each number in the set. The GCF is also known as the greatest common divisor (GCD).

Factors and Divisors

Before we proceed, let's define factors and divisors. A factor of a number is an integer that can be multiplied by another integer to produce the original number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. A divisor of a number is an integer that can divide the number without leaving a remainder. For example, the divisors of 12 are 1, 2, 3, 4, 6, and 12.

Finding the Greatest Common Factor

To find the greatest common factor of 4k, 18k^4, and 12, we need to identify the common factors of these numbers. We can start by listing the factors of each number:

Factors of 4k: 1, 2, 4, k, 2k, 4k
Factors of 18k^4: 1, 2, 3, 6, 9, 18, k, 2k, 3k, 4k, 6k, 9k, 18k, 2k^2, 3k^2, 4k^2, 6k^2, 9k^2, 18k^2, 2k^3, 3k^3, 4k^3, 6k^3, 9k^3, 18k^3, k^4, 2k^4, 3k^4, 4k^4, 6k^4, 9k^4, 18k^4
Factors of 12: 1, 2, 3, 4, 6, 12

Now, let's identify the common factors of these numbers:

Common factors of 4k and 18k^4: 1, 2, 4, k, 2k, 4k
Common factors of 4k and 12: 1, 2, 4
Common factors of 18k^4 and 12: 1, 2, 3, 6

The greatest common factor of 4k, 18k^4, and 12 is the largest number that appears in all three lists of common factors. In this case, the greatest common factor is 2.

Conclusion

In conclusion, the greatest common factor of 4k, 18k^4, and 12 is 2. This is because 2 is the largest number that appears in all three lists of common factors. Understanding the concept of the greatest common factor is essential in mathematics, and it plays a crucial role in solving various mathematical problems.
