HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 10517 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 10517 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 398, 10517 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 398, 10517 is 1.
HCF(398, 10517) = 1
HCF of 398, 10517 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 10517 is 1.
Highest Common Factor of 398,10517 is 1
Step 1: Since 10517 > 398, we apply the division lemma to 10517 and 398, to get
10517 = 398 x 26 + 169
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 169 and 398, to get
398 = 169 x 2 + 60
Step 3: We consider the new divisor 169 and the new remainder 60, and apply the division lemma to get
169 = 60 x 2 + 49
We consider the new divisor 60 and the new remainder 49,and apply the division lemma to get
60 = 49 x 1 + 11
We consider the new divisor 49 and the new remainder 11,and apply the division lemma to get
49 = 11 x 4 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 10517 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(49,11) = HCF(60,49) = HCF(169,60) = HCF(398,169) = HCF(10517,398) .
