The expression 18 + 27 can be simplified by factoring out the GCF which is 9, resulting in the equivalent expression 9(2 + 3). Explanation: Factoring out the Greatest Common Factor (GCF) is a technique used in simplification of expressions and equations.

The GCF of 18 and 32 is 2. The number that is a multiple of 5, greater than 18, and less than 30 is 20. Explanation: The greatest common factor (GCF) of 18 and 32 is 2. To find the GCF, you need to determine the factors of each number and identify the highest factor that is common to both. The factors of 18 are 1, 2, 3, 6, 9, and 18.

Factors of 18: 1, 2, 3, 6, 9, and 18; Step 2: Identify the common factors. Next, we need to identify the common factors between the two numbers, i.e., the factors that both 6 and 18 share. In this case, the common factors are 1, 2, 3, and 6. Step 3: …

The greatest common factor (GCF) of 18 and 225 is 9, while the least common multiple (LCM) of 18 and 225 is 450. Explanation: Greatest Common Factor (GCF) To find the GCF of 18 and 225, we need to find the largest number that divides evenly into both numbers. We can do this by finding the prime factors of each number and finding the common factors.

2024年10月23日 · The numbers involved are 9 and 18. 2. Find the GCF of the coefficients: The GCF of 9 and 18 is 9, because 9 is the largest number that divides both 9 and 18 without leaving a remainder. 3. Factor out the GCF: Once you have identified the GCF as 9, you can factor the expression by dividing each term by 9. - Divide the first term: 9 9 z = z ...

Since 27 is one of the numbers and its only divisors are 1, 3, 9, and 27, the GCF a must be one of these numbers. On the other hand, the LCM of two numbers is the smallest number that both numbers can divide into. If 54 is the LCM, this means that both 27 and the other number must be a factor of 54. The factors of 54 are 1, 2, 3, 6, 9, 18, 27 ...

Finding the GCF is a crucial skill in mathematics, as it helps simplify fractions, factor expressions, and solve equations. It is especially useful when dealing with multiple numbers or when simplifying complex operations. Step-by-step Process for Finding the GCF of 9 and 36. To find the GCF of 9 and 36, we will use a systematic approach.

2024年11月21日 · The GCF of − 18 and − 27 is − 9. This is the largest number that can divide both coefficients − 18 and − 27 without leaving a remainder. 2. Rewrite each term by factoring out − 9: - For the first term − 18 y: We need to find what we multiply by − 9 to get − 18 y. Solving for this, divide − 18 by − 9: − 9 − 18 = 2 ...
