Common factors have to go into both numbers. The only common factor of 20 and 27 is 1.

The lowest common factor of any set of positive integers is always going to be 1.

When you say "do" it, I'm going to assume you mean "find" it. Here's how: -- List all the factors of 45. -- List all the factors of 60. -- Compare the two lists. Boil them down to a short list of only the numbers that appear on both lists. These are the common factors of 45 and 60. "Common" means "same for both". -- Find the biggest number on the short list. That's the "greatest" common factor.

There is always going to be a LCM. Just multiply the two numbers together to get the a common multiple if you cant find one because the two numbers multiplied together is a common multiple.

The one common factor to a business intelligence report is that you are able to keep on top of everything that is going on within a business and then you are able to make strategic decisions much more effectively.

There is no greatest common multiple since numbers keep going on forever. The greatest common factor is 7. The least common multiple is 147

Start of by finding the prime factorization of both these numbers. 348=2²*3*29 426=2*3*71 The greatest common factor is going to be the product of all factors that both numbers share. The only two common factors between 348 and 426 are 2 and 3, so the greatest common factor is 2*3=6.

The GCF is 21.

The greatest COMMON factor depends upon the other number(s) with which 12 has factors in COMMON. However, it will always be one of the factors of 12 which are {1, 2, 3, 4, 6, 12}. Examples: GCF(12, 13) = 1 GCF(12, 14) = 2 GCF(12, 15) = 3 GCF(12, 16) = 4 GCF(12, 18) = 6 GCF(12, 24) = 12You need more than one number to find a GCF.You need at least two numbers to find a GCF.You need at least two numbers to find a GCF.

Common factors have to go into both numbers. The only common factor of 20 and 27 is 1.

So close. We're going to need to know that other number to answer this correctly.

"Common" means "same for both". There can't be anything 'common' about a single number.There's no such thing as a common factor until you have at least 2 numbers.However, if it's any comfort to you, I can tell you now that whatever the other numberturns out to be, the least common factor that it shares with 876 is going to be ' 1 '.

Hint: 7 is a prime number, it has only 1 and itself as factors.The Greatest Common Factor (GCF) is: 1The greatest common factor of two or more numbers is the greatest common divisor of all of them, meaning it's the largest positive integer that divides each of the numbers without remainders. One way to find the GCF is to use prime factorization. Rewrite each number as a product of all prime numbers. Then find the primes that the numbers have in common, multiply those factors together, and you have your GCF! In this example:77 is a prime number. Its only factors are 7 and 1.36Start with 2, the first prime. 36 = 2 x 18. Keep going with 2 until it doesn't work anymore. 36 = 2 x 2 x 9. Keep going. 9 isn't divisible by 2, so try the next prime, 3. 36 = 2 x 2 x 3 x 3. All the factors are prime. You've gone as far as you can go.What prime factors do these numbers have in common? NONE! So that means 1 is the GCF of 7 and 36.Or, you could have noticed that 7 wasn't a factor of 36, so that would leave no answer but 1.The Greatest Common Factor is 1

well, the factors of 42 are: 1, 2, 3, 6, 7, 14, 21, and 42, so it's going to have to be one of those. It's 14

A pair of numbers can have more than one factor because the numbers keep going on.

The following would be easy to program, but slow to run: try all the factors, starting at the smaller of the two numbers, and going down to one, until you find a common factor.A little more tricky, but much faster for larger numbers, is the following property, which I will illustrate with an example. The greatest common factor of 14 and 10 is the same as the greatest common factor of 10 and 4, where 4 is calculated as 14 - 10 (or, faster, to avoid repeated subtraction, 14 % 10 - the remainder of the division). Repeat until you have a remainder of zero: (14, 10), (10, 4), (4, 2), (2, 0). The last non-zero number, in this case 2, is the greatest common factor.The following would be easy to program, but slow to run: try all the factors, starting at the smaller of the two numbers, and going down to one, until you find a common factor.A little more tricky, but much faster for larger numbers, is the following property, which I will illustrate with an example.
