HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 519, 98 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 856, 519, 98 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 856, 519, 98 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 856, 519, 98 is 1.
HCF(856, 519, 98) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 856, 519, 98 is 1.
Step 1: Since 856 > 519, we apply the division lemma to 856 and 519, to get
856 = 519 x 1 + 337
Step 2: Since the reminder 519 ≠ 0, we apply division lemma to 337 and 519, to get
519 = 337 x 1 + 182
Step 3: We consider the new divisor 337 and the new remainder 182, and apply the division lemma to get
337 = 182 x 1 + 155
We consider the new divisor 182 and the new remainder 155,and apply the division lemma to get
182 = 155 x 1 + 27
We consider the new divisor 155 and the new remainder 27,and apply the division lemma to get
155 = 27 x 5 + 20
We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get
27 = 20 x 1 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 856 and 519 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(155,27) = HCF(182,155) = HCF(337,182) = HCF(519,337) = HCF(856,519) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 98 > 1, we apply the division lemma to 98 and 1, to get
98 = 1 x 98 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 98 is 1
Notice that 1 = HCF(98,1) .
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 856, 519, 98?
Answer: HCF of 856, 519, 98 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 856, 519, 98 using Euclid's Algorithm?
Answer: For arbitrary numbers 856, 519, 98 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
