HCF of 15, 27 by Euclid's Divison lemma method can be determined easily by using our free online HCF using Euclid's Divison Lemma Calculator and get the result in a fraction of seconds ie., 3 the largest factor that exactly divides the numbers with r=0.

Highest common factor (HCF) of 15, 27 is 3.

HCF(15, 27) = 3

**Ex:** 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345

Below detailed show work will make you learn how to find HCF of 15,27 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(15,27).

Here 27 is greater than 15

Now, consider the largest number as 'a' from the given number ie., 27 and 15 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b

**Step 1:** Since 27 > 15, we apply the division lemma to 27 and 15, to get

27 = 15 x 1 + 12

**Step 2:** Since the reminder 15 ≠ 0, we apply division lemma to 12 and 15, to get

15 = 12 x 1 + 3

**Step 3:** We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 15 and 27 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) .

Therefore, HCF of 15,27 using Euclid's division lemma is 3.

Here are some samples of HCF using Euclid's Algorithm calculations.

**1. What is the HCF(15, 27)?**
