HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1491, 8171 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1491, 8171 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 1491, 8171 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 1491, 8171 is 1.
HCF(1491, 8171) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1491, 8171 is 1.
Step 1: Since 8171 > 1491, we apply the division lemma to 8171 and 1491, to get
8171 = 1491 x 5 + 716
Step 2: Since the reminder 1491 ≠ 0, we apply division lemma to 716 and 1491, to get
1491 = 716 x 2 + 59
Step 3: We consider the new divisor 716 and the new remainder 59, and apply the division lemma to get
716 = 59 x 12 + 8
We consider the new divisor 59 and the new remainder 8,and apply the division lemma to get
59 = 8 x 7 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1491 and 8171 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(59,8) = HCF(716,59) = HCF(1491,716) = HCF(8171,1491) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
