What is the greatest common factor of 43 and 128?
The greatest common factor for 43 and 32 is 1. Method 1: Factoring completely, we determine that: 32 = 2 * 2 * 2 * 2 * 2 * 1 43 = 43 * 1 The only factor that these two have in common is 1, making this the greatest common factor. Method 2: We notice that 32 is a power of 2 (2 ^ 5, to be exact), so its only unique factors are 1 and 2. Since 43 is odd, it does not have 2 as a factor. Therefore, the only factor that they could have in common is 1, making that the greatest common factor. Method 3: We notice that 43 is a prime number, meaning that its only factors are 1 and itself. Since 32 is not a multiple of 43 (impossible, being smaller), the only common factor they could have is 1.
What is the greatest common factor for 86 129 215?
The greatest factor is 86 which is a factor of 86, though not of 44. The greatest COMMON factor, though not requested, is 2.
What are the common factors and greatest common factor of 86?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 86, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 86 are 1, 2, 43, and 86. Examples: The common factors of 8 and 86 are 1 and 2; the greatest common factor is 2. The common factors of 86 and 387 are 1 and 43; the greatest common factor is 43.
What is the greatest common factor of 215 and 1849?
A common factor is a factor that two or more numbers share. The common factors of 215 and 1849 are: 1, 43.
What is the greatest common factor of 43 and 86?
43 X 2 equals 86. 43 is a prime number. 43 is the GCF of 43 and 86.
What is the greatest common factor of 42 and 86?
The GCF of 42 and 86 is 2. 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
What is the greatest common factor of 60 and 2?
the greatest common factor for 60 and 2 is 1
What is the greatest common factor of 43 and 54?
Answer: 1Definition: 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 the numbers have in common.Method: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 43 are 1 and 43.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The GCF is 1.
What is the greatest common factor of 38 and 4?
The greatest common factor is 2
What is the greatest common factor of 86and154?
The factors of 86 are: 1, 2, 43, 86The factors of 154 are: 1, 2, 7, 11, 14, 22, 77, 154The common factors are: 1, 2The Greatest Common Factor (GCF) is: 2
What is the greatest common factor for 12 and 10?
The Greatest Common Factor of 12 and 10 is 2.
What is the greatest common factor of 2 and 4a?
Since 2 is a factor of 4a and the largest factor of 2 is 2, and thus the greatest common factor cannot be larger than 2, the greatest common factor is 2.
