HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 287, 488 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 771, 287, 488 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 771, 287, 488 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 771, 287, 488 is 1.
HCF(771, 287, 488) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 771, 287, 488 is 1.
Step 1: Since 771 > 287, we apply the division lemma to 771 and 287, to get
771 = 287 x 2 + 197
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 197 and 287, to get
287 = 197 x 1 + 90
Step 3: We consider the new divisor 197 and the new remainder 90, and apply the division lemma to get
197 = 90 x 2 + 17
We consider the new divisor 90 and the new remainder 17,and apply the division lemma to get
90 = 17 x 5 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 771 and 287 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(90,17) = HCF(197,90) = HCF(287,197) = HCF(771,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 488 > 1, we apply the division lemma to 488 and 1, to get
488 = 1 x 488 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 488 is 1
Notice that 1 = HCF(488,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 771, 287, 488?
Answer: HCF of 771, 287, 488 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 771, 287, 488 using Euclid's Algorithm?
Answer: For arbitrary numbers 771, 287, 488 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
