HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 182, 285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 868, 182, 285 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 868, 182, 285 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 868, 182, 285 is 1.

HCF(868, 182, 285) = 1

HCF of 868, 182, 285 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 868, 182, 285 is 1.

Highest Common Factor of 868,182,285 using Euclid's algorithm

Highest Common Factor of 868,182,285 is 1

Step 1: Since 868 > 182, we apply the division lemma to 868 and 182, to get

868 = 182 x 4 + 140

Step 2: Since the reminder 182 ≠ 0, we apply division lemma to 140 and 182, to get

182 = 140 x 1 + 42

Step 3: We consider the new divisor 140 and the new remainder 42, and apply the division lemma to get

140 = 42 x 3 + 14

We consider the new divisor 42 and the new remainder 14, and apply the division lemma to get

42 = 14 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 868 and 182 is 14

Notice that 14 = HCF(42,14) = HCF(140,42) = HCF(182,140) = HCF(868,182) .

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

Step 1: Since 285 > 14, we apply the division lemma to 285 and 14, to get

285 = 14 x 20 + 5

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 5 and 14, to get

14 = 5 x 2 + 4

Step 3: We consider the new divisor 5 and the new remainder 4, and apply the division lemma to get

5 = 4 x 1 + 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 14 and 285 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(285,14) .
