HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 723 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 891, 723 is 3 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 891, 723 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 891, 723 is 3.

HCF(891, 723) = 3

Highest common factor (HCF) of 891, 723 is 3.

Highest Common Factor of 891,723 using Euclid's algorithm

Highest Common Factor of 891,723 is 3

Step 1: Since 891 > 723, we apply the division lemma to 891 and 723, to get

891 = 723 x 1 + 168

Step 2: Since the reminder 723 ≠ 0, we apply division lemma to 168 and 723, to get

723 = 168 x 4 + 51

Step 3: We consider the new divisor 168 and the new remainder 51, and apply the division lemma to get

168 = 51 x 3 + 15

We consider the new divisor 51 and the new remainder 15,and apply the division lemma to get

51 = 15 x 3 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 891 and 723 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(51,15) = HCF(168,51) = HCF(723,168) = HCF(891,723) .
