HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 867, 180, 429, 78 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 867, 180, 429, 78 is 3 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 867, 180, 429, 78 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 867, 180, 429, 78 is 3.
HCF(867, 180, 429, 78) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 867, 180, 429, 78 is 3.
Step 1: Since 867 > 180, we apply the division lemma to 867 and 180, to get
867 = 180 x 4 + 147
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 147 and 180, to get
180 = 147 x 1 + 33
Step 3: We consider the new divisor 147 and the new remainder 33, and apply the division lemma to get
147 = 33 x 4 + 15
We consider the new divisor 33 and the new remainder 15,and apply the division lemma to get
33 = 15 x 2 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 867 and 180 is 3
Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(147,33) = HCF(180,147) = HCF(867,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 429 > 3, we apply the division lemma to 429 and 3, to get
429 = 3 x 143 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 429 is 3
Notice that 3 = HCF(429,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 3, we apply the division lemma to 78 and 3, to get
78 = 3 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 78 is 3
Notice that 3 = HCF(78,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 867, 180, 429, 78?
Answer: HCF of 867, 180, 429, 78 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 867, 180, 429, 78 using Euclid's Algorithm?
Answer: For arbitrary numbers 867, 180, 429, 78 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
