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.
Two pairs of #'s with 10 as their least common multiple: 5x2 1x10
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.
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.
10 and 15
They are: 2 and 9, 1 and 18
Prime numbers have one factor pair.
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.
Any pair of prime or relatively prime numbers.
4
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
Two pairs of #'s with 10 as their least common multiple: 5x2 1x10
They are called relative prime numbers.
Select ALL pairs of numbers that have a least common multiple of 30
The factor pairs of 8 are (8,1)(4,2) The GCF requires at least two numbers.
Two pairs of numbers with 105 as their least common multiple are (15, 105) and (21, 105). This means that both pairs of numbers are multiples of 105 and their only common multiple is 105. The least common multiple is the smallest number that both numbers can divide evenly into.
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.
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.
