HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 779, 404 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 513, 779, 404 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 513, 779, 404 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 513, 779, 404 is 1.
HCF(513, 779, 404) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 513, 779, 404 is 1.
Step 1: Since 779 > 513, we apply the division lemma to 779 and 513, to get
779 = 513 x 1 + 266
Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 266 and 513, to get
513 = 266 x 1 + 247
Step 3: We consider the new divisor 266 and the new remainder 247, and apply the division lemma to get
266 = 247 x 1 + 19
We consider the new divisor 247 and the new remainder 19, and apply the division lemma to get
247 = 19 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 513 and 779 is 19
Notice that 19 = HCF(247,19) = HCF(266,247) = HCF(513,266) = HCF(779,513) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 404 > 19, we apply the division lemma to 404 and 19, to get
404 = 19 x 21 + 5
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 5 and 19, to get
19 = 5 x 3 + 4
Step 3: We consider the new divisor 5 and the new remainder 4, and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 404 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(404,19) .
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 513, 779, 404?
Answer: HCF of 513, 779, 404 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 513, 779, 404 using Euclid's Algorithm?
Answer: For arbitrary numbers 513, 779, 404 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
