HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 771, 406 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 771, 406 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 771, 406 is 1.

HCF(771, 406) = 1

HCF of 771, 406 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 771, 406 is 1.

Highest Common Factor of 771,406 using Euclid's algorithm

Highest Common Factor of 771,406 is 1

Step 1: Since 771 > 406, we apply the division lemma to 771 and 406, to get

771 = 406 x 1 + 365

Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 365 and 406, to get

406 = 365 x 1 + 41

Step 3: We consider the new divisor 365 and the new remainder 41, and apply the division lemma to get

365 = 41 x 8 + 37

We consider the new divisor 41 and the new remainder 37,and apply the division lemma to get

41 = 37 x 1 + 4

We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get

37 = 4 x 9 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 771 and 406 is 1

Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(41,37) = HCF(365,41) = HCF(406,365) = HCF(771,406) .
