The least common factor of any set of numbers is 1, so your problem won't work.
3, 5 and 10,15 have an LCM of 15.
15, 30 and 45,60 have a GCF of 15.

What two pairs of numbers are least common multiples of 10?
Two pairs of #'s with 10 as their least common multiple: 5x2 1x10
What conjecture must be true about the least common multiple of any number pairs in which one number is the greatest common factor of the other number?
Given a pair of numbers, if the lesser of the two is the GCF, the greater of the two is the LCM. This happens when one of the numbers is a factor of the other.
Find two pairs of numbers whose least common multiple is less than the product of the numbers?
4 and 6 6 and 8 Any time the two numbers have a common factor, their LCM will be less than the product because the common factor contributes to the LCM fewer times than it contributes to the product.
What are the pairs of numbers between 8 and 18 that have 5 as their greatest common factor?
10 and 15
What pairs of numbers has an least common multiple of 18?
They are: 2 and 9, 1 and 18
What numbers have the least amount of factor pairs?
Prime numbers have one factor pair.
What is the least common factor of 5 and 12?
The least common factor of 5 and 12 is the smallest number which divides both of them and it is 1, as it is for all pairs of numbers.(It is also the highest common factor of 5 and 12, as 5 and 12 only have one common factor: 1.)The least, or lowest, common multiple of a pair of numbers is the smallest number which is a multiple of both of them, which for 5 and 12 is 60.
What two number pairs whose least common factor is the product of the number?
Any pair of prime or relatively prime numbers.
What 2 pairs of numbers has 8 as the common factor?
4
Are there any pairs of prime numbers that when multiplied do not make their least common multiple?
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
What two pairs of numbers are least common multiples of 10?
Two pairs of #'s with 10 as their least common multiple: 5x2 1x10
What are two pairs of numbers with one as their greatest common factor?
They are called relative prime numbers.
What pair has a greatest common factor of 8?
The factor pairs of 8 are (8,1)(4,2) The GCF requires at least two numbers.
What pair of numbers has a least common multiple of 30?
Select ALL pairs of numbers that have a least common multiple of 30
What conjecture must be true about the least common multiple of any number pairs in which one number is the greatest common factor of the other number?
Given a pair of numbers, if the lesser of the two is the GCF, the greater of the two is the LCM. This happens when one of the numbers is a factor of the other.
Find two pairs of numbers whose least common multiple is less than the product of the numbers?
4 and 6 6 and 8 Any time the two numbers have a common factor, their LCM will be less than the product because the common factor contributes to the LCM fewer times than it contributes to the product.
What are pairs of numbers whose greatest common factor is the same as one of the numbers?
In that case, one of the numbers is a multiple of the other.
