HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 6948, 2121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 406, 6948, 2121 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 406, 6948, 2121 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 406, 6948, 2121 is 1.

HCF(406, 6948, 2121) = 1

HCF of 406, 6948, 2121 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 406, 6948, 2121 is 1.

Highest Common Factor of 406,6948,2121 using Euclid's algorithm

Highest Common Factor of 406,6948,2121 is 1

Step 1: Since 6948 > 406, we apply the division lemma to 6948 and 406, to get

6948 = 406 x 17 + 46

Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 46 and 406, to get

406 = 46 x 8 + 38

Step 3: We consider the new divisor 46 and the new remainder 38, and apply the division lemma to get

46 = 38 x 1 + 8

We consider the new divisor 38 and the new remainder 8,and apply the division lemma to get

38 = 8 x 4 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 406 and 6948 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(38,8) = HCF(46,38) = HCF(406,46) = HCF(6948,406) .

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

Step 1: Since 2121 > 2, we apply the division lemma to 2121 and 2, to get

2121 = 2 x 1060 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 2121 is 1

Notice that 1 = HCF(2,1) = HCF(2121,2) .
