The factors of 78 are 1, 2, 3, 6, 13, 26, 39 and 78. The factors of a number are found by breaking the number down into all the combinations of positive integers that can be combined through multiplication to form the number. This is called factorization.
Know MorePositive integers are the numbers used when counting. Every positive integer has 1 and itself as factors. This is because 1 times any number gives that number as a result. More factors are found by dividing the number by 2 and then 3, working through the integers in succession. Whenever the answer to the division problem is a positive integer, the two numbers are factors of the original number. For example, when 78 is divided by 6 the answer is 13, so 6 and 13 are factors of 78. On the other hand, 78 divided by 8 equals 9.75. That is not a positive integer, so 8 is not a factor of 78. When working with large numbers, a calculator makes the process go quicker.
The prime factorization of a number is a list of all of its prime factors in multiplication form. Prime numbers have no other factors besides 1 and themselves. The prime factorization of 78 is 2 x 3 x 13. Every positive integer that is not a prime number has one unique prime factorization.
Learn more about AlgebraThe factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30. A number is considered the factor of another number when it can be evenly divided into that number.
Full Answer >The factors of the number 38 are 1, 2, 19 and 38. For any positive number, the number 1 and the number itself are factors, so 1 and 38 are inherent factors. Additional numbers that divide 38 evenly are 2 and 19.
Full Answer >The factors of 27 are one, three, nine and 27. The factors of a particular number are those numbers that divide evenly into it. One and the number itself are always factors of any given number.
Full Answer >The factors of 31 are 31,1,-1, and -31. For any number, x, the factors are the set of numbers that can be multiplied by another number to equal x.
