HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 281, 912, 911 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 821, 281, 912, 911 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 821, 281, 912, 911 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 821, 281, 912, 911 is 1.

HCF(821, 281, 912, 911) = 1

Highest Common Factor of 821,281,912,911 using Euclid's algorithm

Highest Common Factor of 821,281,912,911 is 1

Step 1: Since 821 > 281, we apply the division lemma to 821 and 281, to get

821 = 281 x 2 + 259

Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 259 and 281, to get

281 = 259 x 1 + 22

Step 3: We consider the new divisor 259 and the new remainder 22, and apply the division lemma to get

259 = 22 x 11 + 17

We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get

22 = 17 x 1 + 5

We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get

17 = 5 x 3 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 821 and 281 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(259,22) = HCF(281,259) = HCF(821,281) .

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

Step 1: Since 912 > 1, we apply the division lemma to 912 and 1, to get

912 = 1 x 912 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 912 is 1

Notice that 1 = HCF(912,1) .

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

Step 1: Since 911 > 1, we apply the division lemma to 911 and 1, to get

911 = 1 x 911 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 911 is 1

Notice that 1 = HCF(911,1) .
