HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 626, 288 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 489, 626, 288 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, 626, 288 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, 626, 288 is 1.
HCF(489, 626, 288) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 489, 626, 288 is 1.
Step 1: Since 626 > 489, we apply the division lemma to 626 and 489, to get
626 = 489 x 1 + 137
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 137 and 489, to get
489 = 137 x 3 + 78
Step 3: We consider the new divisor 137 and the new remainder 78, and apply the division lemma to get
137 = 78 x 1 + 59
We consider the new divisor 78 and the new remainder 59,and apply the division lemma to get
78 = 59 x 1 + 19
We consider the new divisor 59 and the new remainder 19,and apply the division lemma to get
59 = 19 x 3 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 489 and 626 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(59,19) = HCF(78,59) = HCF(137,78) = HCF(489,137) = HCF(626,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 1, we apply the division lemma to 288 and 1, to get
288 = 1 x 288 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 288 is 1
Notice that 1 = HCF(288,1) .
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, 626, 288?
Answer: HCF of 489, 626, 288 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 489, 626, 288 using Euclid's Algorithm?
Answer: For arbitrary numbers 489, 626, 288 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
