HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 208, 221, 918 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 208, 221, 918 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 208, 221, 918 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 208, 221, 918 is 1.

HCF(208, 221, 918) = 1

Highest common factor (HCF) of 208, 221, 918 is 1.

Highest Common Factor of 208,221,918 using Euclid's algorithm

Highest Common Factor of 208,221,918 is 1

Step 1: Since 221 > 208, we apply the division lemma to 221 and 208, to get

221 = 208 x 1 + 13

Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 13 and 208, to get

208 = 13 x 16 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 208 and 221 is 13

Notice that 13 = HCF(208,13) = HCF(221,208) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 918 > 13, we apply the division lemma to 918 and 13, to get

918 = 13 x 70 + 8

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 8 and 13, to get

13 = 8 x 1 + 5

Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 918 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(918,13) .
