HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 1908 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 1908 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 811, 1908 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 811, 1908 is 1.
HCF(811, 1908) = 1
HCF of 811, 1908 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 811, 1908 is 1.
Highest Common Factor of 811,1908 is 1
Step 1: Since 1908 > 811, we apply the division lemma to 1908 and 811, to get
1908 = 811 x 2 + 286
Step 2: Since the reminder 811 ≠ 0, we apply division lemma to 286 and 811, to get
811 = 286 x 2 + 239
Step 3: We consider the new divisor 286 and the new remainder 239, and apply the division lemma to get
286 = 239 x 1 + 47
We consider the new divisor 239 and the new remainder 47,and apply the division lemma to get
239 = 47 x 5 + 4
We consider the new divisor 47 and the new remainder 4,and apply the division lemma to get
47 = 4 x 11 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 1908 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(47,4) = HCF(239,47) = HCF(286,239) = HCF(811,286) = HCF(1908,811) .
