HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 897, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 897, 715 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 671, 897, 715 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 671, 897, 715 is 1.
HCF(671, 897, 715) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 671, 897, 715 is 1.
Step 1: Since 897 > 671, we apply the division lemma to 897 and 671, to get
897 = 671 x 1 + 226
Step 2: Since the reminder 671 ≠ 0, we apply division lemma to 226 and 671, to get
671 = 226 x 2 + 219
Step 3: We consider the new divisor 226 and the new remainder 219, and apply the division lemma to get
226 = 219 x 1 + 7
We consider the new divisor 219 and the new remainder 7,and apply the division lemma to get
219 = 7 x 31 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 671 and 897 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(219,7) = HCF(226,219) = HCF(671,226) = HCF(897,671) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 715 > 1, we apply the division lemma to 715 and 1, to get
715 = 1 x 715 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 715 is 1
Notice that 1 = HCF(715,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 671, 897, 715?
Answer: HCF of 671, 897, 715 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 671, 897, 715 using Euclid's Algorithm?
Answer: For arbitrary numbers 671, 897, 715 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
