What is the least common multiple of 54 and 72?
The least common multiple of 54 and 72 is 216.
What does find three pairs of numbers for which the least common multiple equals the product of the two numbers mean?
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
What number has 7 as a common factor and 70 as a least common factor?
Let's re-write this. What pair of numbers has 7 as a common factor and 70 as a least common multiple? There are a few answers. One possibility is 14 and 35.
Write the least common multiple of 3 and 12?
3
Write the least common multiple for 2 and 6?
The least common multiple, or LCM of two numbers is the first number that can be found that is divisible by both of them. Factoring the numbers: 2 = 2 6 = 2 * 3 Max values of each shared factor are 21 x 31 so the LCM is 6.
Use oxidation numbers and their least common multiples to write what?
Formulas for compounds
What do you use oxidation numbers and their least common multiples to write?
They are used to write balanced chemical equations.
What is the least common multiple of 8 and 12 write your answer in the grid?
I don't have a grid. The LCM is 24.
How do you show your work on the least common multiple of 3 and 14?
Write out the multiples. 3,6,9,12,15,18,21,24,27,30,33,36,39,42 14,28,42 The LCM is 42.
What are all the possible least common multiple?
That is an infinite number; much too long to write down here.
Why is it important to find the least common multiple?
If you are adding fractions, finding the least common multiple makes the arithmetic easier. For instance if you add 3/4, 5/6 and 1/12 the LCM is 12. In the worst case, you might multiply 4x6x12 to get 288, and have to change each fraction to 288ths!
What number's greatest common factor is 6 and lowest common factor is 72?
All sets of numbers have an LCF of 1, so I'll assume you meant to write least common multiple. 6 and 72 have a GCF of 6 and an LCM of 72. So do 18 and 24.
