HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 875, 986 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 489, 875, 986 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 489, 875, 986 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 489, 875, 986 is 1.
HCF(489, 875, 986) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 489, 875, 986 is 1.
Step 1: Since 875 > 489, we apply the division lemma to 875 and 489, to get
875 = 489 x 1 + 386
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 386 and 489, to get
489 = 386 x 1 + 103
Step 3: We consider the new divisor 386 and the new remainder 103, and apply the division lemma to get
386 = 103 x 3 + 77
We consider the new divisor 103 and the new remainder 77,and apply the division lemma to get
103 = 77 x 1 + 26
We consider the new divisor 77 and the new remainder 26,and apply the division lemma to get
77 = 26 x 2 + 25
We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get
26 = 25 x 1 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 489 and 875 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(77,26) = HCF(103,77) = HCF(386,103) = HCF(489,386) = HCF(875,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 986 > 1, we apply the division lemma to 986 and 1, to get
986 = 1 x 986 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 986 is 1
Notice that 1 = HCF(986,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 489, 875, 986?
Answer: HCF of 489, 875, 986 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 489, 875, 986 using Euclid's Algorithm?
Answer: For arbitrary numbers 489, 875, 986 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
