15=3*5
27=3*3*3
highest common factor=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
The common factors of 36 and 27 are 1, 3 & 9; the highest common factor is 9.
Common factors of 27 and 30 are: 1 and 3.
27 is a prime number. So it's factors are 1 and 27. 22 factors are 1, 2, and 11. So, the highest common factor of 22 and 27 is 1.
The highest common factor is 3
1 and 3, are both the common factors and the GCF of 15 and 27.
The factors of 15 are: 1, 3, 5, 15The factors of 27 are: 1, 3, 9, 27The common factors are: 1, 3
27 and 35's highest common factor is one.
The GCF is 3.
The highest common factor of 54 and 27 is 27
The factors of 15 are 1, 3, 5, and 15 .The factors of 27 are 1, 3, 9, and 27 .The only common factors (factors of both 15 and27) are 1 and 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.
