The common factors of 72 and 86 are: 1 and 2
The common factors are: 1, 2.
The common factors of 72 and 86 are: 1 and 2.
The GCF is 86.
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 86 are: 1, 2, 43, 86 The common factors are: 1, 2
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.
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.
86 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 4 factors of 86 are 1, 2, 43, and 86.The factor pairs of 86 are 1 x 86 and 2 x 43.The proper factors of 86 are 1, 2, and 43 or,if the definition you are using excludes 1, they are 2 and 43.The prime factors of 86 are 2 and 43.The 2 distinct prime factors (listing each prime factor only once) of 86 are 2 and 43.The prime factorization of 86 is 2 x 43.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common. The prime factorization is 2 to the 2nd power times 3 times 7.
To find the sum of all common factors of 12 and 86, we first need to determine the factors of each number. The factors of 12 are 1, 2, 3, 4, 6, and 12, while the factors of 86 are 1, 2, 43, and 86. The common factors of 12 and 86 are 1 and 2. Therefore, the sum of all common factors of 12 and 86 is 1 + 2 = 3.
The common factors are: 1, 2
0.86 = 86 86/100 -> 43/50 (with lowest common factors)
