LCM stands for Lowest Common Multiple, and HCF stands for Highest Common Factor.
The key to telling the difference between these two things is knowing the difference between a multiple and a factor.
A multiple of an integer (whole number) is any integer that appears in its times table. For example, the multiples of 3 are 3, 6, 9, 12, and so on.
A factor of an integer is any integer that divides the integer with no remainder. For example, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.
We use LCM and HCF to compare two (or more) integers. Read More
