What the LCM of 14 and 48?
For any two numbers a and b if a is divisible by b then LCM(a,b) is a.48 is divisible by 6, so LCM(48,6) is 48.
What is the highest common multiple of B and C?
The greatest common multiple of any set of integers is infinite.
What are the common multiples of four and seven?
28, 56, 84 you can always find a common multiple of two numbers by multiplying them (but that won't always be the least common multiple)... the other common multiples can b found by multiplying that number with any other positive integer... for example, if you have two numbers (a and b), then one of their common multiples is a x b (but not always the smallest one), and the others are 2 x a x b, or any other positive integer times a x b
What is the least common multiple of 24 and 9?
The least common multiple of 9 and 24 is 72. To find the LCM, List the multiples of each (starting with 1x) and find the smallest number that appears in both lists: 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, ... 24: 24, 48, 72, 96, 120, 144, 166, ... The common multiples (numbers in both lists) are: 72, 144, ... So the LCM is the lowest number in this list: 72.
How can factors help with finding a common denominator?
There is no such thing as a greatest common denominator. For example, the LEAST common denominator of 3 and 4 is 12, but any multiple of 12 will also be a common denominator. For very small numbers, the fastest way to find the LEAST common denominator (or least common multiple) is to try out multiples of the larger number. For example, to get the least common multiple of 6 and 4: 6 is not a multiple of 4, but the next multiple of 6 (6 x 2 = 12) is, so that's the least common multiple. For numbers of intermediate size, you may want to use prime factorization. That's the method common taught in schools. To repeat with the numbers above: 6 = 3 x 2; 4 = 2 x 2. Gathering all the prime factors, and using duplicates (those that appear in both numbers) only once (or using the highest power that appears in any of the numbers, you get 2 x 2 x 3 = 12. For fairly large numbers, use Euclid's algorithm to find the greatest common factor first. In this case, 6 divided by 4 gives a remainder of 2, and 4 divide by 2 gives a remainder of 0. The last non-zero number in this sequence of divisions is 2, so that's the greatest common factor. Once you have the greatest common factor, use the property that a x b = lcm(a, b) x gcf(a, b). In other words, the least common multiple is equal to a x b / gcf(a, b), in this example, 6 x 4 / 2 = 12.
What is the least common multiple of A and B?
The word "LEAST" (in Least Common Multiple) is a superlative adjective and that means there can be only one. So asking about least common multiples makes no sense.LCM(A, B) = A*B.
Do two whole numbers always have a least common multiple?
Yes. If A and B are any two whole numbers then A*B is a common multiple. Then either A*B is the least common multiple of A and B or one of its factors is.
What is least common multiple of the numbers a and b if a is a factor of b?
The LCM is b.
What is the least common multiple of 2 coprime numbers?
The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.
What is Least common multiple of 8 and B 5?
Their product.
Which of the follwing pairs have a least common multiplyer a is 4 and 6 b is 3 and 8 c is 2 and 12 d is 3 and 6?
a). The least common multiple of 4 and 6 is 12 . b). The least common multiple of 3 and 8 is 24 . c). The least common multiple of 2 and 12 is 12 . d). The least common multiple of 3 and 6 is 6 . Gosh, I guess they all have.
The definition of Common multiples?
In arithmetic and number theory, the least common multiple or lowest common multiple (lcm) or smallest common multiple of two integers a and b is the smallest positive integer that is a multiple of both a and b. Since it is a multiple, it can be divided by a and b without a remainder. If there is no such positive integer, e.g., if a = 0 or b = 0, then lcm(a, b) is defined to be zero.) For example, the least common multiple of the numbers 4 and 6 is 12. When adding or subtracting vulgar fractions, it is useful to find the least common multiple of the denominators, often called the lowest common denominator. For instance, : where the denominator 42 was used because lcm(21, 6) = 42.
What is the least common multiple of 40 and 80 a 120 b 80 c 40?
It is b: 80
What is the least common multiple of 2 B and eight?
That depends on the numerical value of B.
What is a number divisible by 63 and 42?
arithmetic and number theory, the least common multiple(also called the lowest common multiple or smallest common multiple) of two integers a and b, usually denoted by LCM(a, b), is the smallest positive integer that is a multiple of both a and b.LCM(63,42)=126
What is the least common multiple of C B and A?
To answer that, you'll need to have a numerical value for the letters.
Can there be no LCM?
If the numbers are irrational, then yes. If the numbers are rational, no. If they are rational, they can be modelled as a and b, in which case the number ab would be a multiple of both. If there is at least one common multiple, then there must be a lowest common multiple.
