HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 704 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 843, 704 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 843, 704 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 843, 704 is 1.

HCF(843, 704) = 1

HCF of 843, 704 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 843, 704 is 1.

Highest Common Factor of 843,704 using Euclid's algorithm

Highest Common Factor of 843,704 is 1

Step 1: Since 843 > 704, we apply the division lemma to 843 and 704, to get

843 = 704 x 1 + 139

Step 2: Since the reminder 704 ≠ 0, we apply division lemma to 139 and 704, to get

704 = 139 x 5 + 9

Step 3: We consider the new divisor 139 and the new remainder 9, and apply the division lemma to get

139 = 9 x 15 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 843 and 704 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(139,9) = HCF(704,139) = HCF(843,704) .
