The common factors of 12 and 20 are 1, 2 and 4.
12 + 20 = 32
The factors of 32 are 1, 2, 4, 8, 16 and 32.
The prime factorization of 32 is 2 x 2 x 2 x 2 x 2 or 25
Look for a common factor (in this case it's 7), then divide both numbers by this common factor.
See if you can find a common factor. (Hint: in this case, there is indeed a common factor.) Divide both numbers by this common factor to get an equivalent fraction.
A fraction is in simplest form if both its numerator and denominator are whole numbers and their only common factor is 1.
You check whether there is a common factor - in this case, common between 4 and 30. If you find one, you divide both numbers by this common factor.
arabic numbers or decimal numbers
You look for a common factor, then divide both numbers by that common factor.
There cannot be a least common factor of 27, 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 least common factor would be the smallest common factor that all the numbers have, which would be 1.
There is not a least common factor of a single number, such as 48 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 least common factor would be the smallest factor that all the numbers being compared have in common. If there were two or more numbers, the least common factor would be 1.
Find the greatest common factor (GCF) of the numerator and denominator of the fraction. Divide both numbers by the GCF. What is left is the fraction in its simplest form.
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.
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more given numbers.
There is neither a greatest common factor nor common factors of a single number, such as 2060, 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.
There is neither a greatest common factor nor common factors of a single number, such as 93,145,306, 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.
There is neither a greatest common factor nor common factors of a single number, such as 39, 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.
There is neither a greatest common factor nor common factors of a single number, such as 3240, 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.
There is neither a greatest common factor nor common factors of a single number, such as 85,833, 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.
There is neither a greatest common factor nor common factors of a single number, such as 121,630, 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.
