HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 805 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 768, 805 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 768, 805 is 1.

HCF(768, 805) = 1

HCF of 768, 805 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 768, 805 is 1.

Highest Common Factor of 768,805 using Euclid's algorithm

Highest Common Factor of 768,805 is 1

Step 1: Since 805 > 768, we apply the division lemma to 805 and 768, to get

805 = 768 x 1 + 37

Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 37 and 768, to get

768 = 37 x 20 + 28

Step 3: We consider the new divisor 37 and the new remainder 28, and apply the division lemma to get

37 = 28 x 1 + 9

We consider the new divisor 28 and the new remainder 9,and apply the division lemma to get

28 = 9 x 3 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 768 and 805 is 1

Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(37,28) = HCF(768,37) = HCF(805,768) .
