HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 286, 406, 684 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 286, 406, 684 is 2 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 286, 406, 684 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 286, 406, 684 is 2.

HCF(286, 406, 684) = 2

Highest Common Factor of 286,406,684 using Euclid's algorithm

Highest Common Factor of 286,406,684 is 2

Step 1: Since 406 > 286, we apply the division lemma to 406 and 286, to get

406 = 286 x 1 + 120

Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 120 and 286, to get

286 = 120 x 2 + 46

Step 3: We consider the new divisor 120 and the new remainder 46, and apply the division lemma to get

120 = 46 x 2 + 28

We consider the new divisor 46 and the new remainder 28,and apply the division lemma to get

46 = 28 x 1 + 18

We consider the new divisor 28 and the new remainder 18,and apply the division lemma to get

28 = 18 x 1 + 10

We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get

18 = 10 x 1 + 8

We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get

10 = 8 x 1 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 286 and 406 is 2

Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(28,18) = HCF(46,28) = HCF(120,46) = HCF(286,120) = HCF(406,286) .


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

Step 1: Since 684 > 2, we apply the division lemma to 684 and 2, to get

684 = 2 x 342 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 684 is 2

Notice that 2 = HCF(684,2) .
