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.
1, 3, 5 and 15 are the common factors of 15 and 30
You need at least two numbers to find a GCF.There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
The common factors of 30 and 40 are 1, 2, 5, 10
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
The common factors of 30 and 21 are 1 and 3.
The common factors of 30 and 63 are 1 and 3.
The common factors of 30 and 74 are: 1 and 2.
The common factors of 30 and 32 are: 1 and 2
The common factors of 25 and 30 are 1 and 5.
The LCM is the product divided by the GCF18 factors to [2*3*3]30 factors to [2*3*5]common factors are [2*3] so GCF=618 * 30 / 6 = 90â—„
Common factors of 27 and 30 are: 1 and 3.
Common factors of 30 and 16 are: 1 and 2.
