HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1247, 8711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1247, 8711 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 1247, 8711 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 1247, 8711 is 1.
HCF(1247, 8711) = 1
HCF of 1247, 8711 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1247, 8711 is 1.
Highest Common Factor of 1247,8711 is 1
Step 1: Since 8711 > 1247, we apply the division lemma to 8711 and 1247, to get
8711 = 1247 x 6 + 1229
Step 2: Since the reminder 1247 ≠ 0, we apply division lemma to 1229 and 1247, to get
1247 = 1229 x 1 + 18
Step 3: We consider the new divisor 1229 and the new remainder 18, and apply the division lemma to get
1229 = 18 x 68 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 1247 and 8711 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(1229,18) = HCF(1247,1229) = HCF(8711,1247) .
