**gcd**(48,18), divide 48 by 18 to get aquotient of 2 and a remainder of 12. Then divide 18 by 12 to get aquotient of 1 and a remainder of 6. Then divide 12 by 6 to get aremainder of 0, which means that 6 is the

**gcd**.

Hereof, how do you find the GCD of a fraction?

Simplifying **fractions** To do that, we need to **calculate** the **GCD**of the numerator and the denominator, and then divide both by this**GCD**. For example, to simplify the **fraction** we**calculate** the **GCD** of 312 and 845, then we divide thetop and bottom of this **fraction** by the **GCD** we justfound.

Furthermore, is GCD and HCF same? Examples of greatest common factor or highest commonfactor or greatest common divisor are discussed here. In greatestcommon factor (G.C.F)or highest common factor (**H.C.F**) orgreatest common divisor (**G.C.D**), we know that there is nodifference between them. 1. Greatest common factor (G.C.F) of 96and 64 = 32.

In this way, how do you find the GCD of 3 numbers?

To **find** the greatest common factor (**GCF**)between **numbers**, take each **number** and write its primefactorization. Then, **identify** the factors common to each**number** and multiply those common factorstogether.

What is the GCF of 12 and 30?

We found the factors and prime factorization of **12and 30**. The biggest common factor number is the **GCF**number. So the **greatest common factor 12 and 30** is6.
