No.
The Greatest Common Factor (GCF) is: 41The Least Common Multiple (LCM) is: 246
Any set of factors that had 18 as a common multiple would also have multiples of 18 in common, so 18 can't be greatest. 9 and 6 have 18 as their least common multiple.
For practical purposes, there are greatest common factors and least common multiples. The greatest common multiple of any set of integers is infinite.
multiples: Least Common Multiple
The least common multiple is 30. The greatest common factor is 3.
Multiples of 26 include 26, 52, 78, 104, 130 and so on. You need at least two numbers to find a GCF.
No, they are factors.
When doing fractions it is the greatest common factor (GCF) and the least common multiple (LCM). You want the GCF when you are reducing fractions to their simplest form. When changing the denominators to a common one, you want the LCM.
No, 2 and 28 are not multiples of 56, they are factors.
They're infinite. You're probably looking for the greatest common factor or least common multiple.
Any multiple of the least common multiple (264) is a common multiple, so there is no greatest.
No, they are factors.
