HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 827, 486 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 827, 486 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 827, 486 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 827, 486 is 1.
HCF(827, 486) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 827, 486 is 1.
Step 1: Since 827 > 486, we apply the division lemma to 827 and 486, to get
827 = 486 x 1 + 341
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 341 and 486, to get
486 = 341 x 1 + 145
Step 3: We consider the new divisor 341 and the new remainder 145, and apply the division lemma to get
341 = 145 x 2 + 51
We consider the new divisor 145 and the new remainder 51,and apply the division lemma to get
145 = 51 x 2 + 43
We consider the new divisor 51 and the new remainder 43,and apply the division lemma to get
51 = 43 x 1 + 8
We consider the new divisor 43 and the new remainder 8,and apply the division lemma to get
43 = 8 x 5 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 827 and 486 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(43,8) = HCF(51,43) = HCF(145,51) = HCF(341,145) = HCF(486,341) = HCF(827,486) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 827, 486?
Answer: HCF of 827, 486 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 827, 486 using Euclid's Algorithm?
Answer: For arbitrary numbers 827, 486 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
