HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 351, 976 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 830, 351, 976 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, 351, 976 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, 351, 976 is 1.
HCF(830, 351, 976) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 830, 351, 976 is 1.
Step 1: Since 830 > 351, we apply the division lemma to 830 and 351, to get
830 = 351 x 2 + 128
Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 128 and 351, to get
351 = 128 x 2 + 95
Step 3: We consider the new divisor 128 and the new remainder 95, and apply the division lemma to get
128 = 95 x 1 + 33
We consider the new divisor 95 and the new remainder 33,and apply the division lemma to get
95 = 33 x 2 + 29
We consider the new divisor 33 and the new remainder 29,and apply the division lemma to get
33 = 29 x 1 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 830 and 351 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(33,29) = HCF(95,33) = HCF(128,95) = HCF(351,128) = HCF(830,351) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 976 > 1, we apply the division lemma to 976 and 1, to get
976 = 1 x 976 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 976 is 1
Notice that 1 = HCF(976,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 830, 351, 976?
Answer: HCF of 830, 351, 976 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 830, 351, 976 using Euclid's Algorithm?
Answer: For arbitrary numbers 830, 351, 976 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
