HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 825, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 585, 825, 86 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 585, 825, 86 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 585, 825, 86 is 1.

HCF(585, 825, 86) = 1

Highest common factor (HCF) of 585, 825, 86 is 1.

Highest Common Factor of 585,825,86 using Euclid's algorithm

Highest Common Factor of 585,825,86 is 1

Step 1: Since 825 > 585, we apply the division lemma to 825 and 585, to get

825 = 585 x 1 + 240

Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 240 and 585, to get

585 = 240 x 2 + 105

Step 3: We consider the new divisor 240 and the new remainder 105, and apply the division lemma to get

240 = 105 x 2 + 30

We consider the new divisor 105 and the new remainder 30,and apply the division lemma to get

105 = 30 x 3 + 15

We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get

30 = 15 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 585 and 825 is 15

Notice that 15 = HCF(30,15) = HCF(105,30) = HCF(240,105) = HCF(585,240) = HCF(825,585) .

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

Step 1: Since 86 > 15, we apply the division lemma to 86 and 15, to get

86 = 15 x 5 + 11

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 11 and 15, to get

15 = 11 x 1 + 4

Step 3: We consider the new divisor 11 and the new remainder 4, and apply the division lemma to get

11 = 4 x 2 + 3

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

4 = 3 x 1 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 86 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(86,15) .
