The first step to finding the common prime factors is to list the prime factors of both numbers. For 12 and 45, the prime factors are: 12 = 2x2x3 45 = 3x3x5 The next step is to identify which prime factors are shared by both. In this case, both use a 3. Thus, 3 is the only common prime factor of 12 and 45.

Just 3.

Just 3.

The GCF of 10 and 45 is 5 The factors of 10 are 1, 2, 5, and 10. The factors of 45 are 1, 3, 5, 9, 15, and 45. The largest factor they have in common is 5, so 5 is the greatest common factor. Or, you can use prime factors. The prime factors of 10 are 2 and 5. The prime factors of 45 are 3, 3, and 5. The prime factors they have in common are a single 5, so 5 is the greatest common factor.

The GCF of 21 and 45 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 21 are 1, 3, 7, and 21. The factors of 45 are 1, 3, 5, 9, 15, and 45. 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 21 are 3 and 7. The prime factors of 45 are 3, 3, and 5. The prime factors in common are a single 3, so the greatest common factor is 3.

The GCF of 32 and 45 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 32 are 1, 2, 4, 8, 16, and 32. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1. Therefore, 1 is the greatest common factor, which means they are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 32 are 2, 2, 2, 2, and 2. The prime factors of 45 are 3, 3, and 5. They have no prime factors in common, so they are relatively prime.

The common factors of 27 and 45 are 1, 3, and 9. The greatest common factor of 27 and 45 is 9. 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 27 are 1, 3, 9, and 27. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1,3, and 9. Therefore, the greatest common factor is 9. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor. The prime factors of 27 are 3, 3, and 3. The prime factors of 45 are 3, 3, and 5. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.

The greatest common factor of 8 and 45 is 1. The numbers 8 and 45 have no prime factors in common.

The prime factors of 45 are 3 and 5. Among the factors of 45, (3,5) and (5,9) are co-prime.

The greatest common factor of 45 and 55 is 5 To determine GCF you first find the prime factors of each number. For 45 this is (5, 3, 3). For 55 this is (11, 5). Then you take the product of the prime factors that they have in common. In this case the only prime factor they have in common is 5 so the answer is just 5. For a better illustration of the rule look at 45 and 30. Prime factors of 45 are (5, 3, 3) Prime factors of 30 are (5, 3, 2) The prime factors in common are 5 and 3 and the product of these numbers is 15. Therefore the GCF of 45 and 30 is 15.

The LCM of 32 and 45 is 1440. 32 and 45 have no common factors. We call this relatively prime. When you have relatively prime numbers, their LCM is their product.Since 32 and 45 share no common factors, the LCM would be 32*45 = 1440.

The Prime Factors of 45 are 3, 5
