what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
How can you find the LCM of a set of a numbers given their greatest common factor without listing the multiples of the numbers?
If you have two numbers, multiply them together and divide that total by the GCF. The result will be the LCM.
What is the LCM of 77 and 20?
The only common factor between them is 1, so just multiply the numbers together: 77 x 20 = 1540
What is the gcf of 90 and 27?
Prime factor each number. Collect the factors that are common. Multiply the numbers together and get it. 90=2x5x3x3 27=3x3x3 3x3=9
What is the highest common factor of 24 and 28?
To find the highest common factor of two numbers you first need to break them down into their prime factors. In this case: 24 = 2x2x2x3 28 = 2x2x7 The next step is to identify the common factors. In this case, both numbers have two 2s as a factor. We multiply these together to get the HCF: 2x2=4 Thus 4 is the highest common factor of 24 and 28.
What is the greates common factor of 12 and 13?
To get the greatest common factor you must multiply the two numbers together, in this case giving you 156.
How can you get a factor?
Factors are the numbers you multiply together to get another number
How is the greatest common factor of two numbers found if you know the prime common to the numbers?
If there's only one prime common to the numbers, that's the GCF. If there's more than one, multiply them together. That's the GCF.

What is factor tree of a number?
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
What does factoer mean in math?
Factor Noun- the numbers that are multiplied together to get a product. Verb- to find the numbers that multiply together to get the product.
What is the LCM of 122 and 133?
Factor both of the numbers. 122=61X2 133=19X7 Since there are no common factors, you will have to multiply the two numbers together to get the LCM. 122X133=16,226 Answer: 16,226

What is the greatest common factor of 105 and147?
To find the greatest common factor of two numbers, you first need to break those numbers down into their prime factors. For 105 and 147 this is: 105 = 3x5x7 147 = 3x7x7 The next step is to identify any common prime factors. In this case, both numbers have a 3 as a prime factor, and a 7 as a prime factor. Multiply these together to get the GCF: 3x7 = 21 Thus the greatest common factor of 105 and 147 is 21.
What are the common factors of 15 and 25?
The greatest common factor is the highest number that divides exactly into two or more numbers. Factors are numbers you can multiply together to get another number. Therefore, the common factors of 15 and 25 are 5 and 1.
