Answer:
Explanation:
the least common multiple is the lowest number that can be multiplied by any other number to equal both of the given numbers. the greatest common factor is the largest number that can be divided out of both of the given numbers.
This is math not history.
A least common multiple (A.K.A LCM) is the smallest multiple that's divisible between two (or more)numbers.
So let's take 2 and 3 for an example. The smallest multiple that's divisible between 2 and 3 is 6.
Let's take 4 and 2 as an example. The smallest multiple that's divisible by 4 and 2, is 4.
---------------------------------------------------------------------------
The greatest common factor (A.K.A GCF) is the biggest factor between 2 (or more) numbers.
Let's take 6 and 3 as an example.
The factors of 6 are 1, 2, 3, 6.
Factors of 3: 1, 3.
So the GCF is 3.
Let's take 8 and 20
20's factors: 1, 2, 4, 5, 10, 20
8's factors: 1, 2, 4, 8.
Therefore, the GCF is 4.
