Yes only the one and it is 1
The factors of 35 are: 1, 5, 7, 35.
The Least Common Denominator of 57 and 35 is 1.
The common factors of 27 and 57 are 1 and 3
All numbers having more than two factors are composite numbers. Factors of 35 are 1, 5, 7, and 35. Factors of 57 are 1, 3, 19, and 57. Factors of 87 are 1, 3, 29, and 87. Since 35, 57, and 87 all have more than 2 factors, they are composite numbers.
Common factors of 57 and 93 are: 1 and 3.
Common factors of 12 and 57 are: 1 and 3.
Both 1 and 19 can divide into both 19 and 57.
27 and 57 have two common factors: 1, 3.
The common factors are: 1, 19
There are not a greatest common factor, a least common factor, or common factors of a single number, such as 57, 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. Thus, since there are not two or more numbers to compare, there are no common factors.
The factors of 57 are 1, 3, 19, and 57. For them to be common, they need to be compared to another set of factors. You need at least two numbers to find a GCF.
The fraction 38/57 cannot be reduced any further because 38 and 57 do not have any common factors other than 1.
