HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 827, 217, 285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 827, 217, 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 827, 217, 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 827, 217, 285 is 1.

HCF(827, 217, 285) = 1

Highest common factor (HCF) of 827, 217, 285 is 1.

Highest Common Factor of 827,217,285 using Euclid's algorithm

Highest Common Factor of 827,217,285 is 1

Step 1: Since 827 > 217, we apply the division lemma to 827 and 217, to get

827 = 217 x 3 + 176

Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 176 and 217, to get

217 = 176 x 1 + 41

Step 3: We consider the new divisor 176 and the new remainder 41, and apply the division lemma to get

176 = 41 x 4 + 12

We consider the new divisor 41 and the new remainder 12,and apply the division lemma to get

41 = 12 x 3 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 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 827 and 217 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(41,12) = HCF(176,41) = HCF(217,176) = HCF(827,217) .

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

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

285 = 1 x 285 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 285 is 1

Notice that 1 = HCF(285,1) .
