What is the GCF and LCM of 30 and 40?
30 = 3 x 1040 = 4 x 10The GCF of 30 and 40 is 10.30 x 4 = 12040 x 3 = 120The LCM of 30 and 40 is 120.
What is the GCF for these numbers 3 and 5?
The GCF is 1.
What is the GCF of these numbers 345 253 and 115?
gcf for these numbers 345 253 and 115 is 23.
What two numbers have 1 as there gcf?
Prime and relatively prime numbers all have a GCF of 1.
What is the easiest way to find the GCF?
I am asssuming that the numbers are too large for you to simply see them and "know" their GCF. The easiest way to find the GCF of 2 numbers is the Euclidean method. It is somewhat awkward to explain but once understood, is very easy to use. The idea here is to make the numbers that you are dealing with smaller and smaller so as to simplify the problem. Suppose you start with the two numbers p and q where p > q. Assume that they are not equal for if p = q, then their GCF is p (or q). The GCF of p and q is the same as the GCF of the smaller number, (say q), and p-q. Repeat this process and keep going until the two numbers are the same. So, for example, ket us try to find the GCF of 1836 and 1428 GCF(1836, 1428)] = GCF(1428, 1836-1428) = GCF(1428, 408) = GCF(408, 1428-408) = GCF(408, 1020) = GCF(408, 1020-408) = GCF(408, 612) = GCF(408, 612-408) = GCF(408, 204) = GCF(204, 408-204) = GCF(204, 204) The two numbers are the same so STOP! The answer is 204. It is not a particularly fast method, but it is simple: all you need to now is subtraction.
The LCM of two numbers is 60The GCF of the same numbers are 4What are the numbers?
12 and 20
The LCM of two numbers is 120.The GCF of the same two numbers is 4What are the numbers?
4 and 120
Can the GCF of two different numbers is the LCM of the numbers?
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
Can the GCF of 2 different numbers is the LCM of the numbers?
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
Can two numbers have the same greatest common factor?
Two numbers have a GCF. Two sets of two numbers may have the same GCF.
Does the greatest common factor of two numbers have to be the same?
The same as what? The GCF of two numbers will be the same; the GCF of 3 and 9 will always be 3. The GCF of 9 and 12 will also always be 3, but the GCF of 4 and 12 will always be 4.
Which of these numbers doesn't have the same gcf 16 8 24 20?
The GCF of those numbers is 4. If 20 disappeared, the GCF of the remaining numbers would be 8.
How do you change GCF into a LCM with 3 numbers?
The product of the GCF and the LCM is the same as the product of the original two numbers. Divide the product of the original numbers by the GCF. The result will be the LCM.
What number has the same GCF as 30?
30 doesn't have a GCF. You need at least two numbers to have a GCF.
What is the GCF of two square numbers?
When you are trying to find the GCF of two numbers and one of the numbers is a multiple of the other, the GCF will be the smaller of the two numbers. The GCF of 3 and 9 is 3.
Can two numbers have the same LCM as their GCF?
Only if they're the same number. The LCM and GCF of 10 and 10 is 10.
How can you find a GCF?
Example: GCF of 6 and 12= 2 Example 2: GCF of 54 and 6=9 List all the factors of the numbers you use, then if the numbers you have when you list the factors have the same number in both sets of numbers, that is your GCF
