What is the greatest common factor of 9 and 12?
The greatest common factor is the largest number that two numbers can both be divided by to yield a whole number. 9 3 = 3 and 12 3 = 4. By making factor trees you can identify the largest common factors of two numbers. 9 = 3 ⋅ 3 and 12 = 2 ⋅ 2 ⋅ 3, in this case the only common factor is 3 and therefore the greatest.
What are the factors of 12?
Factors are the numbers you multiply together to get another number: There can be many factors of a number. Example: All the factors of 12 2 × 6 = 12, but also 3 × 4 = 12, and of course 1 × 12 = 12. So 1, 2, 3, 4, 6 and 12are factors of 12.
What is 1818 divided by 2 to get 9?
18 divided by 2 equals 9 which shows it divided evenly. b) Further on we have to figure out how to make the decomposition of 9 because it is not a prime number. If we try to divide it by 2 that is not correct as it does not divide evenly.
What numbers do 12 and 9 go into?
To calculate the greatest common factor of 12 and 9, we need to factor each number (factors of 12 = 1, 2, 3, 4, 6, 12; factors of 9 = 1, 3, 9) and choose the greatest factor that exactly divides both 12 and 9, i.e., 3.
What is the highest common multiple of 9 and 12?
3Answer: HCF of 9 and 12 is 3.
What is the least common factor of 9 and 12?
36Answer: LCM of 9 and 12 is 36.
What's the lowest common multiple of 9 and 12?
36LCM of 12 and 9 is 36.
What is the HCF of 9?
Factors of 9 = 1, 3 and 9. Therefore, common factor of 6 and 9 = 1 and 3. Highest common factor (H.C.F) of 6 and 9 = 3. Therefore, 3 is H.C.F.
How do you find the HCF?
How to Find HCF?Step 1: Write each number as a product of its prime factors. This method is called here prime factorization.Step 2: Now list the common factors of both the numbers.Step 3: The product of all common prime factors is the HCF ( use the lower power of each common factor)
What is the HCF of 9 12 and 15?
Greatest common factor (GCF) of 9, 12, 15 is 3.
What is the highest common factor of 12?
HCF Example The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.
What is 9 divided by 3?
9 divided by 3 equals 3 and so we can say that it divided evenly. Moreover please note that 3 is a prime number (actually is the one after 2) so the prime factorization is done. The result of the decomposition process is:
What is the next prime number to take into consideration when decomposing 45?
If we try to divide it by 2 that is not the right solution as it does not divide evenly. The next prime number you have to take into consideration is 3.
