Published Feb 16, 2026
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
What are factors pairs of 4?
The positive pair factors of 4 are (1, 4) and (2, 2).
What is the GCF of 4 and 8?
GCF of 4 and 8 by Listing Common Factors There are 3 common factors of 4 and 8, that are 1, 2, and 4. Therefore, the greatest common factor of 4 and 8 is 4.
What is the HCF of 4 8?
Prime factorization of 4 and 8 is (2 × 2) and (2 × 2 × 2) respectively. As visible, 4 and 8 have common prime factors. Hence, the HCF of 4 and 8 is 2 × 2 = 4.
What is the GCF of 9 and 15?
3
Answer: GCF of 9 and 15 is 3.
How to find the GCF of a number?
To find the GCF of numbers using factoring list out all the factors of each number List of positive integer factors of 8 that divides 8 without a remainder. List of positive integer factors of 20 that divides 20 without a remainder. List of positive integer factors of 48 that divides 48 without a remainder.
Which is the most common factor in GCF?
List of positive integer factors of 20 that divides 20 without a remainder. List of positive integer factors of 48 that divides 48 without a remainder. We found the factors of 8, 20, 48 . The biggest common factor number is the GCF number. So the Greatest Common Factor 8, 20, 48 is 4.
How to calculate the GCF and lcm of two numbers?
The formula of LCM is LCM (a,b) = ( a x b) / GCF (a,b) Here are some samples of LCM of two or more Numbers calculations. To find the GCF of numbers using factoring list out all the factors of each number List of positive integer factors of 8 that divides 8 without a remainder.
How to find the GCF of 36, 48?
On finding the GCF of 36,48 we get the Greatest Common Factor as 12 Now, Divide the GCF i.e., 12 with the multiplied number before ie., 10 and make the integer result into decimal. By dividing the GCF we get = 12/10 = 1.2 On doing, we will get the end result ie., GCF of 3.6,4.8 is 1.2
