HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1247, 8381 i.e. 29 the largest integer that leaves a remainder zero for all numbers.
HCF of 1247, 8381 is 29 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, 8381 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, 8381 is 29.
HCF(1247, 8381) = 29
HCF of 1247, 8381 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, 8381 is 29.
Highest Common Factor of 1247,8381 is 29
Step 1: Since 8381 > 1247, we apply the division lemma to 8381 and 1247, to get
8381 = 1247 x 6 + 899
Step 2: Since the reminder 1247 ≠ 0, we apply division lemma to 899 and 1247, to get
1247 = 899 x 1 + 348
Step 3: We consider the new divisor 899 and the new remainder 348, and apply the division lemma to get
899 = 348 x 2 + 203
We consider the new divisor 348 and the new remainder 203,and apply the division lemma to get
348 = 203 x 1 + 145
We consider the new divisor 203 and the new remainder 145,and apply the division lemma to get
203 = 145 x 1 + 58
We consider the new divisor 145 and the new remainder 58,and apply the division lemma to get
145 = 58 x 2 + 29
We consider the new divisor 58 and the new remainder 29,and apply the division lemma to get
58 = 29 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 1247 and 8381 is 29
Notice that 29 = HCF(58,29) = HCF(145,58) = HCF(203,145) = HCF(348,203) = HCF(899,348) = HCF(1247,899) = HCF(8381,1247) .
