HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 520 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 520 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 838, 520 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 838, 520 is 2.
HCF(838, 520) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 520 is 2.
Step 1: Since 838 > 520, we apply the division lemma to 838 and 520, to get
838 = 520 x 1 + 318
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 318 and 520, to get
520 = 318 x 1 + 202
Step 3: We consider the new divisor 318 and the new remainder 202, and apply the division lemma to get
318 = 202 x 1 + 116
We consider the new divisor 202 and the new remainder 116,and apply the division lemma to get
202 = 116 x 1 + 86
We consider the new divisor 116 and the new remainder 86,and apply the division lemma to get
116 = 86 x 1 + 30
We consider the new divisor 86 and the new remainder 30,and apply the division lemma to get
86 = 30 x 2 + 26
We consider the new divisor 30 and the new remainder 26,and apply the division lemma to get
30 = 26 x 1 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 838 and 520 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(30,26) = HCF(86,30) = HCF(116,86) = HCF(202,116) = HCF(318,202) = HCF(520,318) = HCF(838,520) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 838, 520?
Answer: HCF of 838, 520 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 838, 520 using Euclid's Algorithm?
Answer: For arbitrary numbers 838, 520 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
