WebThe greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators. Created by Sal Khan. WebGo through the following steps to find factors of 21.

WebLet us consider the example given below: For example – The GCF of 18, 21 is 3. Because the factors of the number 18 and 21 are: Factors of 18 = 2×9 =2×3×3. Factors of 21 = 3×7. Here, the number 3 is common in both the factors of numbers. Hence, the greatest common factor of 18 and 21 is 3. Similarly, the GCF of 10, 15 and 25 is 5. WebShow Solution. The factored form of the polynomial 25b3+10b2 25 b 3 + 10 b 2 is 5b2(5b+2) 5 b 2 ( 5 b + 2). You can check this by doing the multiplication. 5b2(5b+2) =25b3+10b2 5 b 2 ( 5 b + 2) = 25 b 3 + 10 b 2. Note that if you do not factor the greatest common factor at first, you can continue factoring, rather than start all over.
