Find two numbers that have 2 3 and 5 as factors?
30 & 60.
How do you find a common factor?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. One way to find them is to list all the factors of a set of numbers. Example 30 and 42 1, 2, 3, 5, 6, 10, 15, 30 1, 2, 3, 6, 7, 14, 21, 42 1, 2, 3 and 6 appear on both lists. They are the common factors of 30 and 42.
What factor is not a factor of 66?
To find the factors that are not factors, find the factors of the number. All numbers that are not listed are not factors. 66: 1 x 66 2 x 33 3 x 22 6 x 11 The factors are 1, 2, 3, 6, 11, 22, 33, and 66. All other numbers are not factors of 66.
Numbers with 3 factors?
The squares of all prime numbers above 2 have exactly 3 factors.
What is the answer of three numbers have 2 factors in math?
Prime numbers have two factors. 2, 3 and 5 are prime numbers.
Find the least common multiple of 4 and 9?
To find the least common multiple (LCM), first factor each of the numbers. The factors of 4 are 2*2. The factors of 9 are 3*3. List the factors of the first number, 4, which is 2*2. List all factors from the second number that are not included in the first number, which is 3*3. The LCM is 2*2*3*3 or the original numbers 4*9 = 36. The LCM of 4 & 9 is 36.
Is there prime numbers in the factors of 6?
Yes, the factors of 6 are 1, 2, 3, 6. 2 and 3 are prime numbers.
What are the prime factors of 18?
The prime factors of 18 are 2 and 3.To find the prime factors of 18, find any two factors of 18, such as 2 and 9.2 X 9 = 18Since 2 is a prime number, find two factors of 9, but don't drop the 2.2 X 3 X 3 = 18.Since 2 and 3 are both prime numbers, 2 X 3 X 3 is the prime factorization of 18.2 and 3 are prime.
How do you use prime factorization to find the GCF of three numbers?
You can find the prime factors of all three numbers, combine (multiply) those numbers and remove redundant factors. So if your numbers are 4, 6 and 8, then those factors are (2*2), (3*2), and (2*2*2) respectively. The GCF is 24 or (2*2*2*3). This is because 24 can be written as a multiple of all three numbers because 24 can be written as a multiple of 2 4 and 6. (2*2*3*(2)) (2*3*(4)) and (2*2*(6)). If this is still unclear you can check the Wikipedia Article on LCM.
Which of the factors of 36 are prime numbers and explain how you know?
2 and 3 are the prime factors of 36. Of the factors of 36, 2 and 3 are the only prime numbers.
How do you figure greatest common factor?
To find the greatest common factor (GCF), first find the prime factorization of the two numbers. The GCF is the product of all of the prime factors the two numbers have in common. If two numbers have no common factors, the GCF is 1. (Since all numbers are divisible by 1.) Example: Find the GCF of 60 and 24. Prime factors of 60: 2, 2, 3, 5 Prime factors of 24: 2, 2, 2, 3 Common factors: 2, 2, 3 GCF: 2x2x3=12 Example: Find the GCF of 17 and 21. Prime factors of 17: 17 Prime factors of 21: 3, 7 Common factors: None (1). GCF: 1
36 have an numbers factors find at least 5 other numbers?
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36
