HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 281, 358 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 281, 358 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 423, 281, 358 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 423, 281, 358 is 1.
HCF(423, 281, 358) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 423, 281, 358 is 1.
Step 1: Since 423 > 281, we apply the division lemma to 423 and 281, to get
423 = 281 x 1 + 142
Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 142 and 281, to get
281 = 142 x 1 + 139
Step 3: We consider the new divisor 142 and the new remainder 139, and apply the division lemma to get
142 = 139 x 1 + 3
We consider the new divisor 139 and the new remainder 3,and apply the division lemma to get
139 = 3 x 46 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 423 and 281 is 1
Notice that 1 = HCF(3,1) = HCF(139,3) = HCF(142,139) = HCF(281,142) = HCF(423,281) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 358 > 1, we apply the division lemma to 358 and 1, to get
358 = 1 x 358 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 358 is 1
Notice that 1 = HCF(358,1) .
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 423, 281, 358?
Answer: HCF of 423, 281, 358 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 423, 281, 358 using Euclid's Algorithm?
Answer: For arbitrary numbers 423, 281, 358 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
