HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 352, 473, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 352, 473, 728 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 352, 473, 728 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 352, 473, 728 is 1.
HCF(352, 473, 728) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 352, 473, 728 is 1.
Step 1: Since 473 > 352, we apply the division lemma to 473 and 352, to get
473 = 352 x 1 + 121
Step 2: Since the reminder 352 ≠ 0, we apply division lemma to 121 and 352, to get
352 = 121 x 2 + 110
Step 3: We consider the new divisor 121 and the new remainder 110, and apply the division lemma to get
121 = 110 x 1 + 11
We consider the new divisor 110 and the new remainder 11, and apply the division lemma to get
110 = 11 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 352 and 473 is 11
Notice that 11 = HCF(110,11) = HCF(121,110) = HCF(352,121) = HCF(473,352) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 728 > 11, we apply the division lemma to 728 and 11, to get
728 = 11 x 66 + 2
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 2 and 11, to get
11 = 2 x 5 + 1
Step 3: 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 11 and 728 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(728,11) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 352, 473, 728?
Answer: HCF of 352, 473, 728 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 352, 473, 728 using Euclid's Algorithm?
Answer: For arbitrary numbers 352, 473, 728 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
