HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 619, 263 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 619, 263 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 391, 619, 263 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 391, 619, 263 is 1.
HCF(391, 619, 263) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 619, 263 is 1.
Step 1: Since 619 > 391, we apply the division lemma to 619 and 391, to get
619 = 391 x 1 + 228
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 228 and 391, to get
391 = 228 x 1 + 163
Step 3: We consider the new divisor 228 and the new remainder 163, and apply the division lemma to get
228 = 163 x 1 + 65
We consider the new divisor 163 and the new remainder 65,and apply the division lemma to get
163 = 65 x 2 + 33
We consider the new divisor 65 and the new remainder 33,and apply the division lemma to get
65 = 33 x 1 + 32
We consider the new divisor 33 and the new remainder 32,and apply the division lemma to get
33 = 32 x 1 + 1
We consider the new divisor 32 and the new remainder 1,and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 391 and 619 is 1
Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(65,33) = HCF(163,65) = HCF(228,163) = HCF(391,228) = HCF(619,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 263 > 1, we apply the division lemma to 263 and 1, to get
263 = 1 x 263 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 263 is 1
Notice that 1 = HCF(263,1) .
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 391, 619, 263?
Answer: HCF of 391, 619, 263 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 391, 619, 263 using Euclid's Algorithm?
Answer: For arbitrary numbers 391, 619, 263 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
