HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 235, 153 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 235, 153 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 342, 235, 153 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 342, 235, 153 is 1.
HCF(342, 235, 153) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 235, 153 is 1.
Step 1: Since 342 > 235, we apply the division lemma to 342 and 235, to get
342 = 235 x 1 + 107
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 107 and 235, to get
235 = 107 x 2 + 21
Step 3: We consider the new divisor 107 and the new remainder 21, and apply the division lemma to get
107 = 21 x 5 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 342 and 235 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(107,21) = HCF(235,107) = HCF(342,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 153 > 1, we apply the division lemma to 153 and 1, to get
153 = 1 x 153 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 153 is 1
Notice that 1 = HCF(153,1) .
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 342, 235, 153?
Answer: HCF of 342, 235, 153 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 342, 235, 153 using Euclid's Algorithm?
Answer: For arbitrary numbers 342, 235, 153 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
