What are the common factors of 45 and 135?
The common factors of 25 and 45 are: 1 and 5
What are the prime factors of 13 and 30?
13 is a prime factor of itself Prime factors of 30 are: 2, 3 and 5
What is the greatest common factor using prime factorization for 30 and 135?
2 x 3 x 5 = 30 3 x 3 x 3 x 5 = 135 3 x 5 = 15, the GCF
What two numbers have a common factor of 30?
There are not common factors of 30 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.
What is the greatest common factor of 45 and 55?
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.
What is the greatest common factor of 135 and 30?
The greatest common factor of 30 and 135 is 15One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135.The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 30 are 2, 3, and 5.The prime factors of 135 are 3, 3, 3, and 5.The prime factors in common are 3 and 5, so the greatest common factor is 3 x 5 = 15.
What is the greatest common factor of 30 45 56 99 135 and 165 using prime factors?
Factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30 Factors of 45 are 1, 3, 5, 9, 15, and 45 Factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56 Factors of 99 are 1, 3, 9 11, 33, and 99 Factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135 Factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165 There are no common factors, so the greatest common factor is 1. The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 30 are 2, 3, and 5. The prime factors of 45 are 3, 3, and 5. The prime factors of 56 are 2, 2, 2, and 7. The prime factors of 99 are 3, 3, and 11. The prime factors of 135 are 3, 3, 3, and 5. The prime factors of 165 are 3, 5, and 11. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.

no, they both have 5 as factors
Is 30 relatively prime to 135?
No. 15 is a common factor
Are 30 and 135 relatively prime?
No, 30 and 135 are not relatively prime.
What are the common prime factors of 30 and 24?
The common prime factors are 2 and 3.
What are the factors of 60 and 135?
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.The prime factors of 60 are: 2, 3, and 5.The factors of 135 are: 1, 3, 5, 9, 15, 27, 45, and 135.The prime factors of 135 are: 3 and 5.
How is the largest factor that 12 and 30 have in common related to the prime factors the two have in common?
The largest factor that 12 and 30 have in common is the product of the two prime factors they have in common.
What is the greatest common factor of 30 and 135 and are they relatively prime?
The gcf is 15; so 30 and 135 are not relatively prime. 30 = 2 x 3 x 5 135 = 33 x 5 hcf = 3 x 5 = 15 If the gcf of two numbers is 1, then they are relatively prime 15 ≠ 1, thus 30 and 135 are not relatively prime.
What are the common factors of 30?
1,30 2,15 3,10 5,6 Common factors are factors that two or more numbers have in common. A single number cannot have common factors. A single number can have factors, prime factors, and proper factors. The factors of 30 are listed above. The prime factors of 30 are 2, 3, and 5.
What pair of numbers is 30 and 18 a common prime factor?
The common prime factors of 18 and 30 are 2 and 3.
What are the common factors of 45 and 135?
The common factors of 25 and 45 are: 1 and 5
