How do you find common multiple?
1.take 2 numbers 2.make both the numbers into their smallest dividends (which are equal to the number when multiplied together, the best way to do this is by using a tree diagram) 3.find out the most amount of times each dividends are in one of the numbers that you are going to be finding the lowest common multiple, not the smallest dividends 4.multiply the numbers you got from step 3 for the lcm example: 6 4 3x2 2x2 3x2x2=12 if you dont want the LOWEST common multiple: 1. find the lowest common multiple 2. multiply it by any whole positive number and youll end up with a common multiple
What is the step to finding the least common denominator?
There are many ways to find the lowest common denominator (LCD). One way is to list out all the factors of both numbers and find the common one. Whichever one is the lowest is the LCD. But if you're using larger numbers you can do trial and error or multiple the denominators.
What is the least common multiple of 10 18 21 by using by using prime factors?
The Least Common Multiple of 10, 18, 21 is 630.
What is the least common multiple of 29 and 7 using the greatest common factor?
The Least Common Multiple of 29, 7 is 203.
What is another word for common denominator?
Common multiple. Incidentally, it need not be the least common multiple. Using the least common multiple instead of any common multiple means that the numbers involved in the calculations are smaller but does not mathematically alter the results.
What is the least common multiple of 20 and 26?
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 26 and 30 is 390.390
What is the least common multiple of 8 and 242 using prime factorization?
The Least Common Multiple of 8, 242 is 968.
What is the least common multiple of 48 and 72 using prime numbers?
The Least Common Multiple of 48, 72 is 144.
What is the least common multiple of 75 and 105 using prime factorization?
The Least Common Multiple of 75, 105 is 525.

Can you give me an example of a word problem using the least common multiple?
The least common multipleof 7 and 9 is 63.
What does the LCM stand for?
LCM = Lowest Common Multiple. This is the smallest number that is common amongst the multiples of two of more other numbers. For example: The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, ... The multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, ... The common multiples of 3 and 5 are: 15, 30, 45, ... The lowest common multiple of 3 and 5 is the smallest of these, namely 15. An example of its use is for adding fractions as using the lowest common multiple of all the denominators ensures the numbers do not get too big (and cumbersome)
