HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 678, 492, 936 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 678, 492, 936 is 6 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 678, 492, 936 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 678, 492, 936 is 6.
HCF(678, 492, 936) = 6
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 678, 492, 936 is 6.
Step 1: Since 678 > 492, we apply the division lemma to 678 and 492, to get
678 = 492 x 1 + 186
Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 186 and 492, to get
492 = 186 x 2 + 120
Step 3: We consider the new divisor 186 and the new remainder 120, and apply the division lemma to get
186 = 120 x 1 + 66
We consider the new divisor 120 and the new remainder 66,and apply the division lemma to get
120 = 66 x 1 + 54
We consider the new divisor 66 and the new remainder 54,and apply the division lemma to get
66 = 54 x 1 + 12
We consider the new divisor 54 and the new remainder 12,and apply the division lemma to get
54 = 12 x 4 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 678 and 492 is 6
Notice that 6 = HCF(12,6) = HCF(54,12) = HCF(66,54) = HCF(120,66) = HCF(186,120) = HCF(492,186) = HCF(678,492) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 936 > 6, we apply the division lemma to 936 and 6, to get
936 = 6 x 156 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 936 is 6
Notice that 6 = HCF(936,6) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 678, 492, 936?
Answer: HCF of 678, 492, 936 is 6 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 678, 492, 936 using Euclid's Algorithm?
Answer: For arbitrary numbers 678, 492, 936 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
