HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 484, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 891, 484, 181 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 891, 484, 181 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 891, 484, 181 is 1.

HCF(891, 484, 181) = 1

Highest common factor (HCF) of 891, 484, 181 is 1.

Highest Common Factor of 891,484,181 using Euclid's algorithm

Highest Common Factor of 891,484,181 is 1

Step 1: Since 891 > 484, we apply the division lemma to 891 and 484, to get

891 = 484 x 1 + 407

Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 407 and 484, to get

484 = 407 x 1 + 77

Step 3: We consider the new divisor 407 and the new remainder 77, and apply the division lemma to get

407 = 77 x 5 + 22

We consider the new divisor 77 and the new remainder 22,and apply the division lemma to get

77 = 22 x 3 + 11

We consider the new divisor 22 and the new remainder 11,and apply the division lemma to get

22 = 11 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 891 and 484 is 11

Notice that 11 = HCF(22,11) = HCF(77,22) = HCF(407,77) = HCF(484,407) = HCF(891,484) .

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

Step 1: Since 181 > 11, we apply the division lemma to 181 and 11, to get

181 = 11 x 16 + 5

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 5 and 11, to get

11 = 5 x 2 + 1

Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 181 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(181,11) .
