HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 670 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 670 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 816, 670 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 816, 670 is 2.
HCF(816, 670) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 670 is 2.
Step 1: Since 816 > 670, we apply the division lemma to 816 and 670, to get
816 = 670 x 1 + 146
Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 146 and 670, to get
670 = 146 x 4 + 86
Step 3: We consider the new divisor 146 and the new remainder 86, and apply the division lemma to get
146 = 86 x 1 + 60
We consider the new divisor 86 and the new remainder 60,and apply the division lemma to get
86 = 60 x 1 + 26
We consider the new divisor 60 and the new remainder 26,and apply the division lemma to get
60 = 26 x 2 + 8
We consider the new divisor 26 and the new remainder 8,and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 816 and 670 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(60,26) = HCF(86,60) = HCF(146,86) = HCF(670,146) = HCF(816,670) .
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 816, 670?
Answer: HCF of 816, 670 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 816, 670 using Euclid's Algorithm?
Answer: For arbitrary numbers 816, 670 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
