What is the lowest common factor of 5 and 11?
There cannot be a least common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the smallest of those common factors is the Least Common Factor.
What if there is no LCM in a fraction problem?
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.
Find the greatest common factor of 60 and 90?
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.
What is the LCM of 2 numbers that have no common factors greater than 1 Give an example?
It is just going to be both multiplied together. Eg. 7 and 4. Start with 7. 7, 14, 21, 28. 4: 4, 8, 12, 16, 20, 24, 28
Do the numbers increase forever?
yes. Numbers never stop. They keep going and going. This is called google
What is the greatest common factor of 18 and 18?
There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
What is the lowest common factor of 5 and 11?
There cannot be a least common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the smallest of those common factors is the Least Common Factor.
What is the greatest common factor of 348 and 426?
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.
What numbers going to 180 that are prime factors?
2, 3 and 5
What is the least common multiple of 14 and 15?
The LCM of 15 and 14 is 210, which is the multiple of the combined prime factors of both numbers (2 x 3 x 5 x 7). Since 14 and 15 have no common factors, the LCM is going to be 15*14=210.The Least Common Multiple (LCM) for 15 14 is 210.
What do the numbers in this set have in common?
We're not going to be able to answer this accurately since you haven't told us what the numbers in the set are.
What numbers could have these factors 1 2 4?
4,8,12,16,20,24,28,32 and it keeps going on just add 4
What is the greatest common factor of the numbers 686 and 42 and 196?
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
What is the greatest common factor of 36 and 7?
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
Does composite numbers have more than 2 factors?
i personaly say i dont know anyways thanks for going on ask.com
Which of these numbers will divide into both 68 and 80 with no remainder?
The common factors of 68 and 80 are 1, 2, and 4 . Next time you ask me to pick the correct item from a list of multiple choices for you, I'm going to expect you to show me the list.
What is the GCM of 21 and 49?
There is no greatest common multiple since numbers keep going on forever. The greatest common factor is 7. The least common multiple is 147
