What is the least common multiple of 49 and 343?
Short answer: There is none.There is not a least common multiple of a single number, such as 23, because there cannot be any form of common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there is not a least common multiple.
What is the difference between a greatest common factor and a least common multiple?
The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. The least common factor of any set of integers is 1.
How are lcm and gcf alike?
The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. Factors go into numbers, numbers go into multiples.
If the least common multiple of 7 and 12 equals 84 what is the greatest common factor?
The GCF is 1.
What is the least common multiple of 8 14 21?
you would have to make a factor tree for 8, 14, and 21. 8 equals 2*2*2. 14 equals 7*2 and 21 equals 7*3. Then you have to see what is the lowest number that they have in common. 8,14,21 do not have a number in commone so there isn't a common multiple.
What least common multiple equals the product of the two numbers?
If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.
Why is the least common multiple of 2 prime numbers their product?
Because prime numbers don't have any common prime factors. Their GCF is 1. Since the product of the GCF and LCM of a pair of numbers equals the product of the numbers, the LCM has to be equal to the product.
What is three pairs of numbers for which the least common multiple equals the product of the two numbers?
14 and 25 36 and 49 5 and 7
What are 3 pairs of numbers which the least common multiple equals the product of the 2 numbers?
4 and 9 22 and 23 37 and 53
Find three pairs of numbers for which the least common multiple equals the product of the two numbers?
16 and 25 23 and 47 27 and 50
What are the numbers being multiplied together to obtain a product?
Multiplicand times multiplier equals product
What numbers have 48 as a lowest common multiple and equals 28?
12 and 16
What are 3 pairs of numbers for which the least common multiple equals the product of the two numbers?
Pick any pair of prime numbers. 5, 7 11, 13 17, 19 Pick any pair of consecutive integers.
How can you use greatest common factor x least common multiple equals A x B?
The product of any two integers is equal to the product of their GCF and LCM. That means you can find any of those four numbers by knowing the other three.
Find three pairs of numbers for which the least common multiple equals the product of two numbers?
Select any two numbers that are coprime: that is they do not have any factor in common. For example, 7 and 13, or 14 and 39, or 8 and 27
When you are finding the product of multiple numbers how can determine if the product will be positive or negative?
A positive times a positive equals a positive, a negative times a negative equals a positive, a negative times a positive equals a negative(vice versa for the last one)
