HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 876, 305, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 876, 305, 189 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 876, 305, 189 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 876, 305, 189 is 1.
HCF(876, 305, 189) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 876, 305, 189 is 1.
Step 1: Since 876 > 305, we apply the division lemma to 876 and 305, to get
876 = 305 x 2 + 266
Step 2: Since the reminder 305 ≠ 0, we apply division lemma to 266 and 305, to get
305 = 266 x 1 + 39
Step 3: We consider the new divisor 266 and the new remainder 39, and apply the division lemma to get
266 = 39 x 6 + 32
We consider the new divisor 39 and the new remainder 32,and apply the division lemma to get
39 = 32 x 1 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 876 and 305 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(39,32) = HCF(266,39) = HCF(305,266) = HCF(876,305) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get
189 = 1 x 189 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1
Notice that 1 = HCF(189,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 876, 305, 189?
Answer: HCF of 876, 305, 189 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 876, 305, 189 using Euclid's Algorithm?
Answer: For arbitrary numbers 876, 305, 189 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
