HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 950, 982 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 950, 982 is 2 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 842, 950, 982 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 842, 950, 982 is 2.
HCF(842, 950, 982) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 842, 950, 982 is 2.
Step 1: Since 950 > 842, we apply the division lemma to 950 and 842, to get
950 = 842 x 1 + 108
Step 2: Since the reminder 842 ≠ 0, we apply division lemma to 108 and 842, to get
842 = 108 x 7 + 86
Step 3: We consider the new divisor 108 and the new remainder 86, and apply the division lemma to get
108 = 86 x 1 + 22
We consider the new divisor 86 and the new remainder 22,and apply the division lemma to get
86 = 22 x 3 + 20
We consider the new divisor 22 and the new remainder 20,and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 842 and 950 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(86,22) = HCF(108,86) = HCF(842,108) = HCF(950,842) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 982 > 2, we apply the division lemma to 982 and 2, to get
982 = 2 x 491 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 982 is 2
Notice that 2 = HCF(982,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 842, 950, 982?
Answer: HCF of 842, 950, 982 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 842, 950, 982 using Euclid's Algorithm?
Answer: For arbitrary numbers 842, 950, 982 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
