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 both numbers have in common. 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 18 are 1, 2, 3, 6, 9, and 18. The factors of 27 are 1, 3, 9, and 27. The factors of 81 are 1, 3, 9, 27, and 81. The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.
To find the greatest common factor, or GCF, you must first identify the factors for each number.For 24, its factors are 1, 2, 3, 4, 6, 8, 12, and 24.For 108, its factors are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108.12 is the highest (or greatest) factor they have in common, so the GCF for 24 and 108 is 12.
The greatest common factor of 27,54 and 63 is 9.
The highest common factor of 54 and 27 is 27
The ONLY common factor of 25 & 27 is... 1
1 and 3
3
The least common factor is: 1
The greatest common factor of 24 and 27 is 3One way to approach this is to look at the difference between 24 and 27, which is 3. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 24 and 27 are divisible by 3, the greatest common factor is 3.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.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 greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 24 are 2, 2, 2, and 3.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.Summary of results:The common factors are 1 and 3.The greatest common factor is 3
1 and 3
They are: 1 and 3
They only have one common factor: 1
The GCF is 3.
The answer is 1.
1 and 3
The GCF is 3.
Common factors of 24 and 27 are 1 and 3
