Want to know how to use Euclid’s algorithm to find the HCF of 200, 445, 145 ? Well, you have come to the right place. In this article, you will be learning about Euclid’s algorithm and how to use it to calculate the HCF with ease.

Take the help of the HCF Calculator using the Euclid Division Algorithm which finds HCF of 200, 445, 145 using Euclid's algorithm i.e 5 quickly.

Euclid’s algorithm is written as a = bq + r. This is known as the division lemma. The variable r varies according to 0 ≤ r ≤ b. We can use this to figure out the HCF of 200,445,145. This is how to do it.

**Step 1:** The first step is to use the division lemma with 445 and 200 because 445 is greater than 200

445 = 200 x 2 + 45

**Step 2:** Here, the reminder 200 is not 0, we must use division lemma to 45 and 200, to get

200 = 45 x 4 + 20

**Step 3:** We consider the new divisor 45 and the new remainder 20, and apply the division lemma to get

45 = 20 x 2 + 5

We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get

20 = 5 x 4 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 5.Therefore, the HCF of 200 and 445 is equal to 5

Notice that 5 = HCF(20,5) = HCF(45,20) = HCF(200,45) = HCF(445,200) .

Now, we must treat the HCF of the first two numbers as the next number in our calculation, and next

**Step 1:** The first step is to use the division lemma with 145 and 5 because 145 is greater than 5

145 = 5 x 29 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 5.Therefore, the HCF of 5 and 145 is equal to 5

Notice that 5 = HCF(145,5) .

**Hence, the HCF of 200, 445, 145 is equal to 5. **
