HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 999, 382, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 999, 382, 163 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 999, 382, 163 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 999, 382, 163 is 1.
HCF(999, 382, 163) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 999, 382, 163 is 1.
Step 1: Since 999 > 382, we apply the division lemma to 999 and 382, to get
999 = 382 x 2 + 235
Step 2: Since the reminder 382 ≠ 0, we apply division lemma to 235 and 382, to get
382 = 235 x 1 + 147
Step 3: We consider the new divisor 235 and the new remainder 147, and apply the division lemma to get
235 = 147 x 1 + 88
We consider the new divisor 147 and the new remainder 88,and apply the division lemma to get
147 = 88 x 1 + 59
We consider the new divisor 88 and the new remainder 59,and apply the division lemma to get
88 = 59 x 1 + 29
We consider the new divisor 59 and the new remainder 29,and apply the division lemma to get
59 = 29 x 2 + 1
We consider the new divisor 29 and the new remainder 1,and apply the division lemma to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 999 and 382 is 1
Notice that 1 = HCF(29,1) = HCF(59,29) = HCF(88,59) = HCF(147,88) = HCF(235,147) = HCF(382,235) = HCF(999,382) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 163 > 1, we apply the division lemma to 163 and 1, to get
163 = 1 x 163 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 163 is 1
Notice that 1 = HCF(163,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 999, 382, 163?
Answer: HCF of 999, 382, 163 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 999, 382, 163 using Euclid's Algorithm?
Answer: For arbitrary numbers 999, 382, 163 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
