HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 839, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 839, 521 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 839, 521 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 839, 521 is 1.
HCF(839, 521) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 839, 521 is 1.
Step 1: Since 839 > 521, we apply the division lemma to 839 and 521, to get
839 = 521 x 1 + 318
Step 2: Since the reminder 521 ≠ 0, we apply division lemma to 318 and 521, to get
521 = 318 x 1 + 203
Step 3: We consider the new divisor 318 and the new remainder 203, and apply the division lemma to get
318 = 203 x 1 + 115
We consider the new divisor 203 and the new remainder 115,and apply the division lemma to get
203 = 115 x 1 + 88
We consider the new divisor 115 and the new remainder 88,and apply the division lemma to get
115 = 88 x 1 + 27
We consider the new divisor 88 and the new remainder 27,and apply the division lemma to get
88 = 27 x 3 + 7
We consider the new divisor 27 and the new remainder 7,and apply the division lemma to get
27 = 7 x 3 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 839 and 521 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(27,7) = HCF(88,27) = HCF(115,88) = HCF(203,115) = HCF(318,203) = HCF(521,318) = HCF(839,521) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 839, 521?
Answer: HCF of 839, 521 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 839, 521 using Euclid's Algorithm?
Answer: For arbitrary numbers 839, 521 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
