Why you would never be asked to find the least common factor of a pair of numbers?
You would never be asked to find the least common factor of a pair of numbers because factors are the numbers that can be multiplied together to get a specific number, and the least common factor of any pair of numbers is always 1. This is because 1 is a factor of every number and is the smallest positive integer. Therefore, finding the least common factor of a pair of numbers would always result in 1, making it unnecessary to calculate.
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.
