The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. Factors go into numbers, numbers go into multiples.
LCM means least common multiple. GCF means greatest common factor. If we have two numbers a and b, then the LCM will be the least number which is a multiple of both a and b. The GCF will be the greatest number that a and b can both divide evenly into.
For example, if the numbers are 6 and 10, then the LCM will be 30 and the GCF will be 2.
Finding the Least Common Multiple you find the smallest number that both numbers will go into.
Finding the Greatest Common Factor, you find the largest number that will go into both numbers evenly.
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
Check it.
30 x 42 = 1260
210 x 6 = 1260
It checks.
The GCF is the largest number that will divide evenly into all the members of a given set of numbers. The LCM is the smallest number that all the members of a given set will divide into.

the gcf is when you try to find the greatest common number between a set of numbers and lcm is when you try to find the lowest multiple out of a set of numbers.

Can the LCM and the GCF of 2 numbers be the same number?
Only if they're the same number. The LCM and GCF of 10 and 10 is 10.
What is the GCF and LCM of 20 and 36?
The GCF is 4.
How do you get the sum of a gcf?
You cannot. LCM{2,6,12} = 12 and GCF{2,6,12} = 2 LCM{4,6,12} = 12 and GCF{4,6,12} = 2 The two sets have the same LCM and GCF but, clearly, their sums are different.
What is the LCM and GCF of 32 56 and 72?
The LCM is 11592. The GCF is 2.
What is the LCM and GCF of 4 and 6?
The GCF refers to whole numbers, not decimals.
What is the LCM and GCF of 60 and 72?
The GCF is 12. The LCM is 360.
Gcf and LCM of 32 80 and 128?
The GCF is: 16The LCM is: 640The LCM is: 640
What is the GCF and LCM of 45 and 150?
The GCF is 15. The LCM is 450.
What is the LCM and GCF of 9 and 33?
The GCF is 3. The LCM is 99.
What is the LCM and gcf of 36 and 48?
Oh, dude, the LCM is the smallest number that both 36 and 48 can divide into evenly, which is 144. And the GCF is the largest number that can divide both 36 and 48 without leaving a remainder, which is 12. So, like, those are the numbers you're looking for. Cool, right?
What is the GCF and LCM of 90 and165?
The GCF is 15. The LCM is 990.
