HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 551, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 803, 551, 167 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 803, 551, 167 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 803, 551, 167 is 1.

HCF(803, 551, 167) = 1

Highest common factor (HCF) of 803, 551, 167 is 1.

Highest Common Factor of 803,551,167 using Euclid's algorithm

Highest Common Factor of 803,551,167 is 1

Step 1: Since 803 > 551, we apply the division lemma to 803 and 551, to get

803 = 551 x 1 + 252

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 252 and 551, to get

551 = 252 x 2 + 47

Step 3: We consider the new divisor 252 and the new remainder 47, and apply the division lemma to get

252 = 47 x 5 + 17

We consider the new divisor 47 and the new remainder 17,and apply the division lemma to get

47 = 17 x 2 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 803 and 551 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(47,17) = HCF(252,47) = HCF(551,252) = HCF(803,551) .

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

Step 1: Since 167 > 1, we apply the division lemma to 167 and 1, to get

167 = 1 x 167 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 167 is 1

Notice that 1 = HCF(167,1) .
