HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 85171 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 85171 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 297, 85171 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 297, 85171 is 1.
HCF(297, 85171) = 1
HCF of 297, 85171 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 85171 is 1.
Highest Common Factor of 297,85171 is 1
Step 1: Since 85171 > 297, we apply the division lemma to 85171 and 297, to get
85171 = 297 x 286 + 229
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 229 and 297, to get
297 = 229 x 1 + 68
Step 3: We consider the new divisor 229 and the new remainder 68, and apply the division lemma to get
229 = 68 x 3 + 25
We consider the new divisor 68 and the new remainder 25,and apply the division lemma to get
68 = 25 x 2 + 18
We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get
25 = 18 x 1 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 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 297 and 85171 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(68,25) = HCF(229,68) = HCF(297,229) = HCF(85171,297) .
