What are some methods you use for finding factors of a number?
tree factor and two answer is i don't know?
How do you use prime factors in everyday life?
Prime factors are part of prime factorizations. Prime factorizations help in finding the GCF and LCM of integers. Finding the GCF helps in reducing fractions. Finding the LCM helps in adding and subtracting unlike fractions. Carpenters do this. Chefs do this. It's entirely possible you will have no need of this, but it's better to know something and not need to use it then not know something you need to use. If you have children of your own, you can help them with their math homework.
In gcf do you use factors or prime factors?
Either one will work. If you're listing factors, use factors. If you're using prime factorization, use prime factors.
How do you work out the lcm when there are indices?
It is the same as finding the LCM of two numbers that have been expressed as a product of their prime factors except that you need to use the highest index for each prime factor.
What are the factors and prime factors of 12 show the work?
The factors of 12 are: 1,2,3,4,6. The prime factors are the prime numbers in the factors. So: 1,2,3 are the prime factors of 12.
What are all the common factors of 12 and 45?
The first step to finding the common prime factors is to list the prime factors of both numbers. For 12 and 45, the prime factors are: 12 = 2x2x3 45 = 3x3x5 The next step is to identify which prime factors are shared by both. In this case, both use a 3. Thus, 3 is the only common prime factor of 12 and 45.
How do you use prime factorization to see if they are relatively prime?
If your numbers have no prime factors in common, they are relatively prime.
Can you use the factors of 36 to find the factors of 360?
Yes. Since 36 x 10 = 360, combine the prime factors of 36 with the prime factors of 10.
How do you show work for finding prime numbers?
Use a factor tree.
What prime factors of 18 are also prime factors of 24?
With the use of prime factorisation the numbers are: 18: 2,3,3 24: 2,2,2,3 The actual factors are for both 18 and 24 are 2 and 3
When do you use GCF and LCM?
Gcf you use when you are finding the greatest factor for the numbers. Lcm you use when you are finding the smallest multiple in the numbers factors
How do you find out the common factors?
you use prime factorization
