HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 631, 426, 408 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 631, 426, 408 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 631, 426, 408 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 631, 426, 408 is 1.

HCF(631, 426, 408) = 1

HCF of 631, 426, 408 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 631, 426, 408 is 1.

Highest Common Factor of 631,426,408 using Euclid's algorithm

Highest Common Factor of 631,426,408 is 1

Step 1: Since 631 > 426, we apply the division lemma to 631 and 426, to get

631 = 426 x 1 + 205

Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 205 and 426, to get

426 = 205 x 2 + 16

Step 3: We consider the new divisor 205 and the new remainder 16, and apply the division lemma to get

205 = 16 x 12 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 631 and 426 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(205,16) = HCF(426,205) = HCF(631,426) .

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

Step 1: Since 408 > 1, we apply the division lemma to 408 and 1, to get

408 = 1 x 408 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 408 is 1

Notice that 1 = HCF(408,1) .
