HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 646, 896, 338 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 646, 896, 338 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 646, 896, 338 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 646, 896, 338 is 2.
HCF(646, 896, 338) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 646, 896, 338 is 2.
Step 1: Since 896 > 646, we apply the division lemma to 896 and 646, to get
896 = 646 x 1 + 250
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 250 and 646, to get
646 = 250 x 2 + 146
Step 3: We consider the new divisor 250 and the new remainder 146, and apply the division lemma to get
250 = 146 x 1 + 104
We consider the new divisor 146 and the new remainder 104,and apply the division lemma to get
146 = 104 x 1 + 42
We consider the new divisor 104 and the new remainder 42,and apply the division lemma to get
104 = 42 x 2 + 20
We consider the new divisor 42 and the new remainder 20,and apply the division lemma to get
42 = 20 x 2 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 646 and 896 is 2
Notice that 2 = HCF(20,2) = HCF(42,20) = HCF(104,42) = HCF(146,104) = HCF(250,146) = HCF(646,250) = HCF(896,646) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 338 > 2, we apply the division lemma to 338 and 2, to get
338 = 2 x 169 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 338 is 2
Notice that 2 = HCF(338,2) .
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 646, 896, 338?
Answer: HCF of 646, 896, 338 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 646, 896, 338 using Euclid's Algorithm?
Answer: For arbitrary numbers 646, 896, 338 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
