HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 328, 455, 716 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 328, 455, 716 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, 455, 716 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, 455, 716 is 1.
HCF(328, 455, 716) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 328, 455, 716 is 1.
Step 1: Since 455 > 328, we apply the division lemma to 455 and 328, to get
455 = 328 x 1 + 127
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 127 and 328, to get
328 = 127 x 2 + 74
Step 3: We consider the new divisor 127 and the new remainder 74, and apply the division lemma to get
127 = 74 x 1 + 53
We consider the new divisor 74 and the new remainder 53,and apply the division lemma to get
74 = 53 x 1 + 21
We consider the new divisor 53 and the new remainder 21,and apply the division lemma to get
53 = 21 x 2 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 328 and 455 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(53,21) = HCF(74,53) = HCF(127,74) = HCF(328,127) = HCF(455,328) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 716 > 1, we apply the division lemma to 716 and 1, to get
716 = 1 x 716 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 716 is 1
Notice that 1 = HCF(716,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 328, 455, 716?
Answer: HCF of 328, 455, 716 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 328, 455, 716 using Euclid's Algorithm?
Answer: For arbitrary numbers 328, 455, 716 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
