What is the GCF of 27 and 27? | Thinkster Math? ›

When you compare the two lists of factors, you can see that the common factor(s) are 1, 3, 9, 27. Since 27 is the largest of these common factors, the GCF of 27 and 27 would be 27.

Solution: The GCF of 7 and 27 is 1.

Solution: Factors of 27 = 1, 3, 9 and 27.

The GCF of 24 and 27 is 3. To calculate the GCF (Greatest Common Factor) of 24 and 27, we need to factor each number (factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24; factors of 27 = 1, 3, 9, 27) and choose the greatest factor that exactly divides both 24 and 27, i.e., 3.

Solution: The GCF of 37 and 27 is 1.

When you compare the two lists of factors, you can see that the common factor(s) are 1, 3, 9, 27. Since 27 is the largest of these common factors, the GCF of 27 and 27 would be 27.

To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

The factors of 27 are 1, 3, 9, 27. So, the least factor of 27 is 1 and the greatest factor is 27 itself.

Factors of 27 are numbers that, when multiplied in pairs give the product as 27. There are overall 4 factors of 27 among which 27 is the biggest factor and its positive factors are 1, 3, 9 and 27. The sum of all factors of 27 is 40. Its Prime Factors are 1, 3, 9, 27, and (1, 27) and (3, 9) are Pair Factors.

Hence, the first 20 multiples of 27 are, 27, 54, 81, 108, 135, 162, 189, 216, 243, 270, 297, 324, 351, 378, 405, 432, 459, 486, 513, and 540.

What is the GCF 28 and 27? ›

As a result, the GCF of 28 and 27 is 1.

The GCF of 27 and 72 is 9. To calculate the GCF of 27 and 72, we need to factor each number (factors of 27 = 1, 3, 9, 27; factors of 72 = 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72) and choose the greatest factor that exactly divides both 27 and 72, i.e., 9.

Solution: The LCM of 27 and 27 is 27.

The common factors for 75,27 are 1,3 . The GCF (HCF) of the numerical factors 1,3 is 3 .

The Highest Common Factor of 27 and 36 is 9. The factors of 27 and 36 are 1, 3, 9, 27 and 1, 2, 3, 4, 6, 9, 12, 18, 36, respectively. Here, the Greatest Common Factor (GCF) of 27 and 36 is 9.

The factors of 16 are 1, 2, 4, 8, 16, and the factors of 27 are 1, 3, 9, 27. Clearly, 1 is the only common factor in both 16 and 27. Hence, we can conclude that the Highest Common Factor of 16 and 27 is 1.

It would be 7. Usually you'd be looking for the GCF of two or more numbers as GCF=Greatest Common Factor meaning the highest number that can be multiplied by something else to create each of the numbers as a product.

When you compare the prime factorization of these two numbers, you can see that there are no matching prime factors. When this is the case, it means that there are no common factors between these two numbers.

The GCF of 7 and 28 is 7. To calculate the GCF of 7 and 28, we need to factor each number (factors of 7 = 1, 7; factors of 28 = 1, 2, 4, 7, 14, 28) and choose the greatest factor that exactly divides both 7 and 28, i.e., 7.
