HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 328, 865, 615 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 328, 865, 615 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 328, 865, 615 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 328, 865, 615 is 1.
HCF(328, 865, 615) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 328, 865, 615 is 1.
Step 1: Since 865 > 328, we apply the division lemma to 865 and 328, to get
865 = 328 x 2 + 209
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 209 and 328, to get
328 = 209 x 1 + 119
Step 3: We consider the new divisor 209 and the new remainder 119, and apply the division lemma to get
209 = 119 x 1 + 90
We consider the new divisor 119 and the new remainder 90,and apply the division lemma to get
119 = 90 x 1 + 29
We consider the new divisor 90 and the new remainder 29,and apply the division lemma to get
90 = 29 x 3 + 3
We consider the new divisor 29 and the new remainder 3,and apply the division lemma to get
29 = 3 x 9 + 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 328 and 865 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(29,3) = HCF(90,29) = HCF(119,90) = HCF(209,119) = HCF(328,209) = HCF(865,328) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 1, we apply the division lemma to 615 and 1, to get
615 = 1 x 615 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 615 is 1
Notice that 1 = HCF(615,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 328, 865, 615?
Answer: HCF of 328, 865, 615 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 328, 865, 615 using Euclid's Algorithm?
Answer: For arbitrary numbers 328, 865, 615 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
