To find the highest common factor of three numbers by using division method is discussed here step by step.

**Step I: **

First of all find the highest common factor (H.C.F) of any two of the given numbers. **Step II: **

Now find the highest common factor (H.C.F) of the third given number and the highest common factor (H.C.F) obtained in Step 1 from first and the second number.

Let us consider some examples to find the highest common factor (H.C.F) of three numbers by division method.

**1. Find highest common factor (H.C.F) of 184, 230 and 276 by using division method. **

**Solution:**

Let us find the highest common factor (H.C.F) of 184 and 230.

Highest common factor of 184 and 230 = 46.

Now find the H.C.F. of 276 and 46.

Highest common factor of 276 and 46 = 46.

Therefore, required **highest common factor (H.C.F) of 184, 230 and 276 = 46**.**2. Find highest common factor (H.C.F) of 136, 170 and 255 by using division method. ****Solution:**

Let us find the highest common factor (H.C.F) of 136 and 170.

Highest common factor of 136 and 170 = 34.

Now find the H.C.F. of 34 and 255.

Highest common factor of 34 and 255 = 17.

Therefore, required **highest common factor (H.C.F) of 136, 170 and 255 = 17**.

**3.** Using long division method, find H.C.F of 891, 1215 and
1377.

**Solution:**

Therefore, highest common factor of 891 and 1215 is 81 and now we shall find H.C.F of 81 and 1377.

Therefore, H.C.F. of 891, 1215 and 1377 is 81.
