HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 526, 861, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 526, 861, 13 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 526, 861, 13 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 526, 861, 13 is 1.
HCF(526, 861, 13) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 526, 861, 13 is 1.
Step 1: Since 861 > 526, we apply the division lemma to 861 and 526, to get
861 = 526 x 1 + 335
Step 2: Since the reminder 526 ≠ 0, we apply division lemma to 335 and 526, to get
526 = 335 x 1 + 191
Step 3: We consider the new divisor 335 and the new remainder 191, and apply the division lemma to get
335 = 191 x 1 + 144
We consider the new divisor 191 and the new remainder 144,and apply the division lemma to get
191 = 144 x 1 + 47
We consider the new divisor 144 and the new remainder 47,and apply the division lemma to get
144 = 47 x 3 + 3
We consider the new divisor 47 and the new remainder 3,and apply the division lemma to get
47 = 3 x 15 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 526 and 861 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(144,47) = HCF(191,144) = HCF(335,191) = HCF(526,335) = HCF(861,526) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 526, 861, 13?
Answer: HCF of 526, 861, 13 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 526, 861, 13 using Euclid's Algorithm?
Answer: For arbitrary numbers 526, 861, 13 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
