HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 86 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 671, 86 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 671, 86 is 1.
HCF(671, 86) = 1
HCF of 671, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 671, 86 is 1.
Highest Common Factor of 671,86 is 1
Step 1: Since 671 > 86, we apply the division lemma to 671 and 86, to get
671 = 86 x 7 + 69
Step 2: Since the reminder 86 ≠ 0, we apply division lemma to 69 and 86, to get
86 = 69 x 1 + 17
Step 3: We consider the new divisor 69 and the new remainder 17, and apply the division lemma to get
69 = 17 x 4 + 1
We consider the new divisor 17 and the new remainder 1, and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 86 is 1
Notice that 1 = HCF(17,1) = HCF(69,17) = HCF(86,69) = HCF(671,86) .
