HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 171 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 171 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 812, 171 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 812, 171 is 1.
HCF(812, 171) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 171 is 1.
Step 1: Since 812 > 171, we apply the division lemma to 812 and 171, to get
812 = 171 x 4 + 128
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 128 and 171, to get
171 = 128 x 1 + 43
Step 3: We consider the new divisor 128 and the new remainder 43, and apply the division lemma to get
128 = 43 x 2 + 42
We consider the new divisor 43 and the new remainder 42,and apply the division lemma to get
43 = 42 x 1 + 1
We consider the new divisor 42 and the new remainder 1,and apply the division lemma to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 812 and 171 is 1
Notice that 1 = HCF(42,1) = HCF(43,42) = HCF(128,43) = HCF(171,128) = HCF(812,171) .
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 812, 171?
Answer: HCF of 812, 171 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 812, 171 using Euclid's Algorithm?
Answer: For arbitrary numbers 812, 171 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
