The GCF is 6.
The factors of 45 are: 1, 3, 5, 9, 15, 45The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72The common factors are: 1, 3, 9everyone knows that you have to find the factors of 45 and then 72 and then find what they have in commen and then find the highest now work it out ya self
The prime factors of 15 are 3 and 5. The prime factors of 18 are 2 and 3. The highest power of each of these is 1.
Factors of 45: 1, 3, 5, 9, 15, 45 Factors of 18: 1, 2, 3, 6, 9, 18 Common Factors: 1, 3, 9
The greatest common factor of 36 and 90 is 18.The common factors of 36 and 90 are 1, 2, 3, 6, 9, and 18.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods: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 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The common factors are 1, 2, 3, 6, 9, and 18. Therefore, the greatest common factor is 18.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 36 are 2, 2, 3, and 3.The prime factors of 90 are 2, 3, 3, and 5.The prime factors in common are 2, 3, and 3, so the greatest common factor is 2 x 3 x 3 = 18.
I think its 18
Common factors of 15 and 18 are: 1 and 3.
find the factors of each # and then find the highest common factor: 18=1,2,3,6,9,18 19=1,19 gcd(19,18)=1
The HCF is 18
The highest common factors are 1 and 2 .They are also the lowest common factors.
Common factors of 18, 30, and 48 are: 1, 2, 3, and 6.
You need at least two numbers to find a GCF.
The GCF is 6.
Highest common factor is 18
The highest common factor of 54 and 90 is 18
The GCF is 6.
The Greatest Common Factor (GCF) is: 6
In order to be a common factor there has to be 2 numbers.The factors of 1824 are 25 x 3 x 19If you were meaning the highest common factor of 18 and 24 then the answer is: Factors of 18: 2x32 Factors of 24: 23 x 3 Therefore the highest common factor is 2x3=6
