HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 426, 678, 999 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 426, 678, 999 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 426, 678, 999 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 426, 678, 999 is 3.
HCF(426, 678, 999) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 426, 678, 999 is 3.
Step 1: Since 678 > 426, we apply the division lemma to 678 and 426, to get
678 = 426 x 1 + 252
Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 252 and 426, to get
426 = 252 x 1 + 174
Step 3: We consider the new divisor 252 and the new remainder 174, and apply the division lemma to get
252 = 174 x 1 + 78
We consider the new divisor 174 and the new remainder 78,and apply the division lemma to get
174 = 78 x 2 + 18
We consider the new divisor 78 and the new remainder 18,and apply the division lemma to get
78 = 18 x 4 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 426 and 678 is 6
Notice that 6 = HCF(18,6) = HCF(78,18) = HCF(174,78) = HCF(252,174) = HCF(426,252) = HCF(678,426) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 999 > 6, we apply the division lemma to 999 and 6, to get
999 = 6 x 166 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 999 is 3
Notice that 3 = HCF(6,3) = HCF(999,6) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 426, 678, 999?
Answer: HCF of 426, 678, 999 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 426, 678, 999 using Euclid's Algorithm?
Answer: For arbitrary numbers 426, 678, 999 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
