HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 343, 146, 48 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 343, 146, 48 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 343, 146, 48 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 343, 146, 48 is 1.
HCF(343, 146, 48) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 343, 146, 48 is 1.
Step 1: Since 343 > 146, we apply the division lemma to 343 and 146, to get
343 = 146 x 2 + 51
Step 2: Since the reminder 146 ≠ 0, we apply division lemma to 51 and 146, to get
146 = 51 x 2 + 44
Step 3: We consider the new divisor 51 and the new remainder 44, and apply the division lemma to get
51 = 44 x 1 + 7
We consider the new divisor 44 and the new remainder 7,and apply the division lemma to get
44 = 7 x 6 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 343 and 146 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(44,7) = HCF(51,44) = HCF(146,51) = HCF(343,146) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 1, we apply the division lemma to 48 and 1, to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 48 is 1
Notice that 1 = HCF(48,1) .
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 343, 146, 48?
Answer: HCF of 343, 146, 48 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 343, 146, 48 using Euclid's Algorithm?
Answer: For arbitrary numbers 343, 146, 48 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
