HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 867 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 867 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 491, 867 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 491, 867 is 1.
HCF(491, 867) = 1
HCF of 491, 867 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 491, 867 is 1.
Highest Common Factor of 491,867 is 1
Step 1: Since 867 > 491, we apply the division lemma to 867 and 491, to get
867 = 491 x 1 + 376
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 376 and 491, to get
491 = 376 x 1 + 115
Step 3: We consider the new divisor 376 and the new remainder 115, and apply the division lemma to get
376 = 115 x 3 + 31
We consider the new divisor 115 and the new remainder 31,and apply the division lemma to get
115 = 31 x 3 + 22
We consider the new divisor 31 and the new remainder 22,and apply the division lemma to get
31 = 22 x 1 + 9
We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get
22 = 9 x 2 + 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 491 and 867 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(31,22) = HCF(115,31) = HCF(376,115) = HCF(491,376) = HCF(867,491) .
