HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 326, 847, 15 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 326, 847, 15 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 326, 847, 15 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 326, 847, 15 is 1.
HCF(326, 847, 15) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 326, 847, 15 is 1.
Step 1: Since 847 > 326, we apply the division lemma to 847 and 326, to get
847 = 326 x 2 + 195
Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 195 and 326, to get
326 = 195 x 1 + 131
Step 3: We consider the new divisor 195 and the new remainder 131, and apply the division lemma to get
195 = 131 x 1 + 64
We consider the new divisor 131 and the new remainder 64,and apply the division lemma to get
131 = 64 x 2 + 3
We consider the new divisor 64 and the new remainder 3,and apply the division lemma to get
64 = 3 x 21 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 326 and 847 is 1
Notice that 1 = HCF(3,1) = HCF(64,3) = HCF(131,64) = HCF(195,131) = HCF(326,195) = HCF(847,326) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 15 > 1, we apply the division lemma to 15 and 1, to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 15 is 1
Notice that 1 = HCF(15,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 326, 847, 15?
Answer: HCF of 326, 847, 15 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 326, 847, 15 using Euclid's Algorithm?
Answer: For arbitrary numbers 326, 847, 15 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
