HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 3163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 991, 3163 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 991, 3163 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 991, 3163 is 1.
HCF(991, 3163) = 1
HCF of 991, 3163 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 991, 3163 is 1.
Highest Common Factor of 991,3163 is 1
Step 1: Since 3163 > 991, we apply the division lemma to 3163 and 991, to get
3163 = 991 x 3 + 190
Step 2: Since the reminder 991 ≠ 0, we apply division lemma to 190 and 991, to get
991 = 190 x 5 + 41
Step 3: We consider the new divisor 190 and the new remainder 41, and apply the division lemma to get
190 = 41 x 4 + 26
We consider the new divisor 41 and the new remainder 26,and apply the division lemma to get
41 = 26 x 1 + 15
We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get
26 = 15 x 1 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 3163 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(41,26) = HCF(190,41) = HCF(991,190) = HCF(3163,991) .
