What are the factors of 12 and 15?
The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.
What are the factors of 9 and 15?
GCF of 9 and 15 is the largest possible number that divides 9 and 15 exactly without any remainder. The factors of 9 and 15 are 1, 3, 9 and 1, 3, 5, 15 respectively. There are 3 commonly used methods to find the GCF of 9 and 15 – prime factorization, Euclidean algorithm, and long division.
Which is the greatest factor of 9, 12 and 15?
The first step to find the gcf of 9, 12 and 15 is to list the factors of each number. The factors of 9 are 1, 3 and 9. The factors of 12 are 1, 2, 3, 4, 6 and 12. The factors of 15 are 1, 3, 5 and 15. So, the Greatest Common Factor for these numbers is 3 because it divides all them without a remainder. Read more about Common Factors below.
How to calculate factors of 12 and 15?
So we start with 1, then check 2,3,4,5,6,7,8,9, etc and 12,15 Getting factors is done by dividing 12,15 with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors. Factors are whole numbers or integers that are multiplied together to produce a given number.
What are the Postive factors of the number 12?
The Postive Factors of 12 are therefore all the numbers we used to divide (divisors) above to get an even number. Here is the list of all Postive Factors of 12 in numerical order: 1, 2, 3, 4, 6, and 12. Factors of 12 include negative numbers.
What are the factors of the number 15?
The numbers which are composite in nature such as, 18, 12, 24, 35, etc. have factors for them. Whereas the multiples of 15 are the extended times of 15, such as, 15 , 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315 and so on.
