HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 287, 43 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 843, 287, 43 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 843, 287, 43 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 843, 287, 43 is 1.

HCF(843, 287, 43) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 843, 287, 43 is 1.

Highest Common Factor of 843,287,43 using Euclid's algorithm

Highest Common Factor of 843,287,43 is 1

Step 1: Since 843 > 287, we apply the division lemma to 843 and 287, to get

843 = 287 x 2 + 269

Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 269 and 287, to get

287 = 269 x 1 + 18

Step 3: We consider the new divisor 269 and the new remainder 18, and apply the division lemma to get

269 = 18 x 14 + 17

We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get

18 = 17 x 1 + 1

We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get

17 = 1 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 843 and 287 is 1

Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(269,18) = HCF(287,269) = HCF(843,287) .


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

Step 1: Since 43 > 1, we apply the division lemma to 43 and 1, to get

43 = 1 x 43 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 43 is 1

Notice that 1 = HCF(43,1) .
