1, 3, 5 and 15 are the common factors of 15 and 30
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30. For them to be common, they need to be compared to another set of factors.
Common factors of 9, 15, and 30 are: 1 and 3.
Common factors of 15, 25, and 30 are: 1 and 5.
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 45 are: 1, 3, 5, 9, 15, 45 The common factors are: 1, 3, 5, 15 The Greatest Common Factor: GCF = 15
Factors of 15 are 1, 3, 5, and 15. Factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. Common factors of 15 and 30 are 1, 3, 5, and 15.
The GCF of 30 and 75 is 15 In order to find the HCF of 30 and 75 you must first express them as the product of their prime factors: 30 = 2x3x5 75 = 3x5x5 The next step is to identify any common factors. In this case both numbers have a 3 and a 5 as factors. Multiply these together to find the HCF: 3x5 = 15 Thus the greatest common factor of 30 and 75 is 15.
The common factors of 30 and 45 are: 1, 3, 5, 15.
The common factors of 15 and 30 are 1, 3, 5, and 15. Factors of 15 are 1, 3, 5, and 15. Factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
Since 15 is a factor of 30, all of its factors are common.
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.
1,3,5,15
The GCF is 15.
