Prime factorization.
Example: 30 and 42
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
The pair of numbers 16 and 160 has a GCF of 16 and an LCM of 160.
You need at least two numbers to find a GCF or an LCM and the LCM of those numbers can never be less than the GCF. 12 and 360 have a GCF of 12 and an LCM of 360. So do 60 and 72.
LCM is Least Common Multiple of 2 or more numbers.So, LCM of 1 number i.e. 36 is not defined. GCF is Greatest Common Factor of 2 or more numbers.So, GCF of 1 number i.e. 1 is not defined.
GCF stands for Greatest Common Factor, which is the number two or more numbers share as a factor (the largest one). LCM stands for Least Common Multiple, which is the number that two or more numbers multiply to (the smallest one). An example of GCF: 6 and 9, what is the GCF? 3 An example of LCM: 6 and 9, what is the LCM? 18
LCM=Least common multiple Thus,the least number that multiplies both 15 and 25 is %. sorry about the GCF ?
I factor because the problem I'm solving calls for it. It's the fastest and easiest way to solve for the GCF or LCM.
The LCM of a set of numbers will never be less than the GCF.
The LCM of a set of numbers will never be less than the GCF.
The product of the original numbers is equal to the product of the GCF and LCM. Divide the product of the LCM and GCF by the one number. The answer will be the other.
Only if you're comparing the number to itself. The LCM and GCF of 10 and 10 is 10.
Only if they're the same number. The LCM and GCF of 10 and 10 is 10.
When you are comparing a number to itself. The GCF and LCM of 10 and 10 is 10.
The GCF is the factor, the LCM is the other one.
72,48
5 and 60 have a gcf of 5 and a LCM of 60
Whenever one number is a multiple of the other, the LCM is the larger number and the GCF is the smaller number. The difference is 42.
Only if you're comparing a number to itself. The GCF and LCM of 10 and 10 is 10.
