HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 742, 999 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 830, 742, 999 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 830, 742, 999 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 830, 742, 999 is 1.
HCF(830, 742, 999) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 830, 742, 999 is 1.
Step 1: Since 830 > 742, we apply the division lemma to 830 and 742, to get
830 = 742 x 1 + 88
Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 88 and 742, to get
742 = 88 x 8 + 38
Step 3: We consider the new divisor 88 and the new remainder 38, and apply the division lemma to get
88 = 38 x 2 + 12
We consider the new divisor 38 and the new remainder 12,and apply the division lemma to get
38 = 12 x 3 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 830 and 742 is 2
Notice that 2 = HCF(12,2) = HCF(38,12) = HCF(88,38) = HCF(742,88) = HCF(830,742) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 999 > 2, we apply the division lemma to 999 and 2, to get
999 = 2 x 499 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 999 is 1
Notice that 1 = HCF(2,1) = HCF(999,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 830, 742, 999?
Answer: HCF of 830, 742, 999 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 830, 742, 999 using Euclid's Algorithm?
Answer: For arbitrary numbers 830, 742, 999 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
