HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 912 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 807, 912 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 807, 912 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 807, 912 is 3.

HCF(807, 912) = 3

HCF of 807, 912 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 807, 912 is 3.

Highest Common Factor of 807,912 using Euclid's algorithm

Highest Common Factor of 807,912 is 3

Step 1: Since 912 > 807, we apply the division lemma to 912 and 807, to get

912 = 807 x 1 + 105

Step 2: Since the reminder 807 ≠ 0, we apply division lemma to 105 and 807, to get

807 = 105 x 7 + 72

Step 3: We consider the new divisor 105 and the new remainder 72, and apply the division lemma to get

105 = 72 x 1 + 33

We consider the new divisor 72 and the new remainder 33,and apply the division lemma to get

72 = 33 x 2 + 6

We consider the new divisor 33 and the new remainder 6,and apply the division lemma to get

33 = 6 x 5 + 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 807 and 912 is 3

Notice that 3 = HCF(6,3) = HCF(33,6) = HCF(72,33) = HCF(105,72) = HCF(807,105) = HCF(912,807) .
