What else can I help you with?
When you do LCD in math do you use multiples or factors?
multiples: Least Common Multiple
When is it useful to use factors and multiples?
Factors are useful when you're trying to reduce fractions. Multiples are useful when you're trying to find a least common denominator.
When can you use common multiples and factors?
Use the LCM when you are adding and subtracting unlike fractions. Use the GCF when you are simplifying fractions.
What multiples of 72 can be added to get 21?
All multiples of 72 are greater than 21. If you're looking for factors of 72, use 9 and 12 or 18 and 3
How do you use prime factorization to find three common factors and three common multiples?
you multiply them together
Examples of units you can use to measure mass?
Mass can be measured in -- kilogram, and any of its multiples and sub-multiples -- pound-mass -- slug
What multiples of 24 add up to 19?
There aren't any. All multiples of 24 are greater than 19. If you mean factors, you can use 12, 6 and 1 or 8, 6, 3, 2.
What is the least common factor of 4 and 14 using lists of multiples?
You won't find common factors by using lists of multiples. The least common factor of any set of integers is 1, no matter what you use.
What are strategies for finding factors and multiples?
It would help to have a few specific examples as I am not sure how much depth you want to go into. To find all of the factors of a big number, I find the square root of that number and round down. Then all factors must be equal to or lower than that square root. eg To find the factors of 1200, the square root is 34.6. Round down to 34. Any factors of 1200 must be 34 or less. Then I just try starting from 2 (1 is always a factor), I try to divide by all of the numbers up to 34. Some will not work. So factors of 1200 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 25, 30. To find multiples, use multiplication tables. e.g. multiples of 7 are 7, 14, 21, 28 etc. If you want Lowest Common Multiples, and Greatest Common Factor, then that involves different process.
Why do you use centimetres to measure the length of a ladybug?
I would use a millimetre, but since the SI system allows simple conversions for multiples of ten and factors of ten, that is simply a presentational detail.
How many ways to make 75?
To determine the number of ways to make 75, we need more context. Are we looking at different combinations of numbers, or are we considering factors or multiples of 75? If we are looking at combinations, we could use a partition function or dynamic programming to calculate the number of ways. If we are considering factors or multiples, we would need to find all the factors of 75 and calculate the combinations from there.
What are some multiples of 21 and 17?
I think you mean some common multiples. Since 17 is prime, there are no common factors of 17 and 21. Now the first common multiple will be 21x17. You can use more 21s or more 17s to find additional multiples. Here is one 17x21x21 Here is another 17x17x21
