HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 829, 870 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 829, 870 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 618, 829, 870 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 618, 829, 870 is 1.
HCF(618, 829, 870) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 829, 870 is 1.
Step 1: Since 829 > 618, we apply the division lemma to 829 and 618, to get
829 = 618 x 1 + 211
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 211 and 618, to get
618 = 211 x 2 + 196
Step 3: We consider the new divisor 211 and the new remainder 196, and apply the division lemma to get
211 = 196 x 1 + 15
We consider the new divisor 196 and the new remainder 15,and apply the division lemma to get
196 = 15 x 13 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 618 and 829 is 1
Notice that 1 = HCF(15,1) = HCF(196,15) = HCF(211,196) = HCF(618,211) = HCF(829,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 870 > 1, we apply the division lemma to 870 and 1, to get
870 = 1 x 870 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 870 is 1
Notice that 1 = HCF(870,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 618, 829, 870?
Answer: HCF of 618, 829, 870 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 618, 829, 870 using Euclid's Algorithm?
Answer: For arbitrary numbers 618, 829, 870 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
