HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 834, 170 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 834, 170 is 2 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 834, 170 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 834, 170 is 2.
HCF(834, 170) = 2
HCF of 834, 170 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 834, 170 is 2.
Highest Common Factor of 834,170 is 2
Step 1: Since 834 > 170, we apply the division lemma to 834 and 170, to get
834 = 170 x 4 + 154
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 154 and 170, to get
170 = 154 x 1 + 16
Step 3: We consider the new divisor 154 and the new remainder 16, and apply the division lemma to get
154 = 16 x 9 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 834 and 170 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(154,16) = HCF(170,154) = HCF(834,170) .
