All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors because they are factors that the numbers have in common. 3 is a factor of 12. 3 is a factor of 15. 3 is a common factor of 12 and 15.
Factors are the numbers you multiple together to get another number. 15: 1, 3, 5, 15
85 has four factors.
The common factors of 15, 45, and 75 are the numbers that can evenly divide all three of these numbers. To find the common factors, you can first determine the prime factors of each number: 15 = 3 x 5, 45 = 3 x 3 x 5, and 75 = 3 x 5 x 5. The common factors are the numbers that appear in the prime factorization of all three numbers, which in this case are 3 and 5.
Any whole number (integer) has factors. Factors are numbers that can be divided into another number. For example the factors of 15 are: 1, 3, 5 and 15 (1 times 15 and 3 times 5)
No, they are factors of 15. Factors go into numbers, numbers go into multiples.
There are no common factors of 15 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 15 are 1, 3, 5, and 15.Examples:The common factors of 6 and 15 are 1 and 3.The common factors of 15 and 90 are 1, 3, 5, and 15.1,5,3, and 15.
No, they are composite numbers. The factors of 15 are 1, 3, 5, and 15. The factors of 33 are 1, 3, 11, and 33. Prime numbers have two factors: 1 and the number itself, so 15 and 33 cannot be prime.
1, 3, 5, 15
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a common factor of 9 and 15.
