HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 846, 170 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 846, 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 634, 846, 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 634, 846, 170 is 2.
HCF(634, 846, 170) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 846, 170 is 2.
Step 1: Since 846 > 634, we apply the division lemma to 846 and 634, to get
846 = 634 x 1 + 212
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 212 and 634, to get
634 = 212 x 2 + 210
Step 3: We consider the new divisor 212 and the new remainder 210, and apply the division lemma to get
212 = 210 x 1 + 2
We consider the new divisor 210 and the new remainder 2, and apply the division lemma to get
210 = 2 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 634 and 846 is 2
Notice that 2 = HCF(210,2) = HCF(212,210) = HCF(634,212) = HCF(846,634) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 170 > 2, we apply the division lemma to 170 and 2, to get
170 = 2 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 170 is 2
Notice that 2 = HCF(170,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 634, 846, 170?
Answer: HCF of 634, 846, 170 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 634, 846, 170 using Euclid's Algorithm?
Answer: For arbitrary numbers 634, 846, 170 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
