What are two pairs of numbers that have 10 as their least common multiple?
To find pairs of numbers with 10 as their least common multiple, we need to consider the prime factors of 10, which are 2 and 5. One pair of numbers could be 2 and 10, as their least common multiple is 10. Another pair could be 5 and 10, as their least common multiple is also 10. These pairs have 10 as their least common multiple because they share the prime factors of 10.
What pair of numbers do not have any common multiples?
All numbers have common multiples.
If two is not a common factor of a pair of numbers what other numbers cannot be common factors?
Even numbers.
How small can the least common multiple of pair of numbers be?
Can a pair of numbers have fewer than two common factors?
Yes, a pair of numbers can have fewer than two common factors. This only happens when the numbers are co-prime -- that is, when the numbers have only one common factor. In that case, the common factor is always 1.
What pair of numbers have 4 and 5 as common factors?
20 and 40 have 4 and 5 as common factors.
Is the least common multiple of a pair of numbers ever less then both numbers?
No.
When will the greatest common factor of a pair of numbers equal the least common multiple of the same pair of numbers?
Only if the magnitudes of two numbers are the same.
What is a pair of numbers that has a least common multiple of 36?
12,36
Give all the common prime factors each pair of numbers share?
Okay. Give us a pair of numbers.
What is the least common factor of 10and 25?
The least common factor of any set of numbers is 1.
What are the common factors for each pair of numbers 11 and 15?
The common factor is 1.
