HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 171, 441, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 171, 441, 80 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 917, 171, 441, 80 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 917, 171, 441, 80 is 1.
HCF(917, 171, 441, 80) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 171, 441, 80 is 1.
Step 1: Since 917 > 171, we apply the division lemma to 917 and 171, to get
917 = 171 x 5 + 62
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 62 and 171, to get
171 = 62 x 2 + 47
Step 3: We consider the new divisor 62 and the new remainder 47, and apply the division lemma to get
62 = 47 x 1 + 15
We consider the new divisor 47 and the new remainder 15,and apply the division lemma to get
47 = 15 x 3 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 917 and 171 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(47,15) = HCF(62,47) = HCF(171,62) = HCF(917,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 441 > 1, we apply the division lemma to 441 and 1, to get
441 = 1 x 441 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 441 is 1
Notice that 1 = HCF(441,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get
80 = 1 x 80 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1
Notice that 1 = HCF(80,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 917, 171, 441, 80?
Answer: HCF of 917, 171, 441, 80 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 917, 171, 441, 80 using Euclid's Algorithm?
