HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 75 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 891, 75 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, 75 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, 75 is 3.

HCF(891, 75) = 3

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 891, 75 is 3.

Highest Common Factor of 891,75 using Euclid's algorithm

Highest Common Factor of 891,75 is 3

Step 1: Since 891 > 75, we apply the division lemma to 891 and 75, to get

891 = 75 x 11 + 66

Step 2: Since the reminder 75 ≠ 0, we apply division lemma to 66 and 75, to get

75 = 66 x 1 + 9

Step 3: We consider the new divisor 66 and the new remainder 9, and apply the division lemma to get

66 = 9 x 7 + 3

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

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 891 and 75 is 3

Notice that 3 = HCF(9,3) = HCF(66,9) = HCF(75,66) = HCF(891,75) .
