3
The common factor of both 15 and 27 is 3.
The GCF of 15, 27, and 39 is 3.
1 and 3, are both the common factors and the GCF of 15 and 27.
15=3*5 27=3*3*3 highest common factor=3
The GCF of 15 and 27 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 15 are 1, 3, 5, and 15. The factors of 27 are 1, 3, 9, and 27. The common factors are 1 and 3. Therefore, 3 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 15 are 3 and 5. The prime factors of 27 are 3, 3, and 3. The prime factors in common are a single 3, so the greatest common factor is 3.

Answer: 3Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 21 are 1, 3, 7, and 21.The factors of 27 are 1, 3, 9, and 27.The common factors are 1 and 3. Therefore, the greatest common factor is 3.
The factors of 15 are: 1, 3, 5, 15.The factors of 27 are: 1, 3, 9, 27.The common factors are: 1, 3.The Greatest Common Factor (GCF) is: 3
Factors of 27: 1, 3, 9, 27Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30GCF (27, 30) = 3
