What is the least common factor in 12 15 and 22?
Prime factors of 12 are 22 and 3 Prime factors of 15 are 3 and 5 Prime factors of 22 are 2 and 11 Least common multiple = 22*3*5*11 = 660
What is the least common factor of 9 and 15?
Most of the time, math questions are about the greatest common factor or the least common multiple, not the least common factor. The least common factor of any two numbers would typically be 1. The factors of 15 are 1, 3, 5, and 15. The factors of 9 are 1, 3, and 9. The greatest common factor is 3. The prime factors of 15 are 3 and 5. The prime factors of 9 are 3 and 3. So, take the 3 and 5 prime factors of 15, and then the second 3 prime factor of 9, multiply them together, so 3 x 5 x 3 = 45 is the least common multiple.
What is the least common multiple of 2 3 5 and 9?
To determine the least common multiple of more than two numbers, determine the prime factors of all numbers. Then, determine the prime factors they have in common with at least one of the other numbers and the ones that are not in common. The prime factor of 2 is 2. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 9 are 3 and 3. The prime factor 3 is a factor in common in one pair. Multiply all the factors together and divide by any that were in common with the other numbers. Therefore, the least common multiple is 2 x 3 x 5 x 9 ÷ 3 = 90
What is a common prime factor?
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
What is the least common factor of 87 30and 3?
The greatest common factor is the greatest number that divides two numbers. The procedure for finding the greatest common factor is:List the prime factors of each number.Multiply together all the factors that both the numbers have in common. If there are no common prime factors, the GCF is 1.In this case, the prime factors of 87 are 3 and 29 because 3*29 = 87 and 3 and 29 are prime.andthe prime factor of 3 is 3 because 3 is prime.Therefore, the common factors are a single prime = 3Therefore, the greatest common factor of 83 and 3 is 3.
What is common prime factors?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
What is the least common multiple of 95 and 38?
The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 38 and 95 is 19. (See related question "What is the greatest common factor of 38 and 95?" for this calculation.) So, the least common multiple is 38 x 95 ÷ 19 = 190. Alternately, to determine the least common multiple, determine their prime factors. The prime factors of 38 are 2 and 19. The prime factors of 95 are 5 and 19. Then, determine the common prime factors and the ones that are not shared. The common prime factors are a single 19. The remaining factor of 38 is 2. The remaining factor of 95 is 5. Multiply these together to obtain the least common multiple. 19 x 2 x 5 = 190
What is the least common factor of 24 and 28 prime factor?
The least common prime factor of 24 and 28 is 2.
What is the least common factor of 5 and 7?
The least common factor of any set of integers is 1.
What is the least common factor of 24 and 33?
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 33 are 1, 3, 11, and 33. The common factors are 1 and 3. The least (smallest) common factor is 1. The smallest common prime factor is 3.
What is the least common factor of 16 and 21?
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
Is there a common prime factor of 16 and 25?
There are no common prime factors!
