HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 357, 289, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 357, 289, 443 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 357, 289, 443 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 357, 289, 443 is 1.
HCF(357, 289, 443) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 357, 289, 443 is 1.
Step 1: Since 357 > 289, we apply the division lemma to 357 and 289, to get
357 = 289 x 1 + 68
Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 68 and 289, to get
289 = 68 x 4 + 17
Step 3: We consider the new divisor 68 and the new remainder 17, and apply the division lemma to get
68 = 17 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 357 and 289 is 17
Notice that 17 = HCF(68,17) = HCF(289,68) = HCF(357,289) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 443 > 17, we apply the division lemma to 443 and 17, to get
443 = 17 x 26 + 1
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 1 and 17, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 443 is 1
Notice that 1 = HCF(17,1) = HCF(443,17) .
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 357, 289, 443?
Answer: HCF of 357, 289, 443 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 357, 289, 443 using Euclid's Algorithm?
Answer: For arbitrary numbers 357, 289, 443 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
