Factors of 27 by Prime Factorization & Factor Tree Method
Factors of 27 are 1, 3, 9, and 27 while factor pair of 27 are (1, 27), and (3, 9). A factor of a number is an integer that can completely divide a number without leaving any remainder. In this case, factors of 27 are numbers that can completely divide 27. Factors of 27 can be obtained by finding the prime factorization of 27 or integer factorization of the number. Prime factorization is the process of breaking a number down into set of prime numbers whose product results in the original number.
- Factors of 27 are 1, 3, 9 and 27.
- Negative factors of 27 are -1, -3, -9, and -27.
- Prime factors of 27 is 3
- Sum of factors of 27 is 40.
- Prime factorization of 27 is \(3\times 3\times 3\).
Factors of 27 Solved Examples
Que 1: Find the common factors of 18 and 27.
Ans 1: We need to find the factors of 18 and 27.
Factors of 18 = 1, 2, 3, 6, 9 and 18.
