HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 795, 624, 312 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 795, 624, 312 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 795, 624, 312 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 795, 624, 312 is 3.
HCF(795, 624, 312) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 795, 624, 312 is 3.
Step 1: Since 795 > 624, we apply the division lemma to 795 and 624, to get
795 = 624 x 1 + 171
Step 2: Since the reminder 624 ≠ 0, we apply division lemma to 171 and 624, to get
624 = 171 x 3 + 111
Step 3: We consider the new divisor 171 and the new remainder 111, and apply the division lemma to get
171 = 111 x 1 + 60
We consider the new divisor 111 and the new remainder 60,and apply the division lemma to get
111 = 60 x 1 + 51
We consider the new divisor 60 and the new remainder 51,and apply the division lemma to get
60 = 51 x 1 + 9
We consider the new divisor 51 and the new remainder 9,and apply the division lemma to get
51 = 9 x 5 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma 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 795 and 624 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(51,9) = HCF(60,51) = HCF(111,60) = HCF(171,111) = HCF(624,171) = HCF(795,624) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 312 > 3, we apply the division lemma to 312 and 3, to get
312 = 3 x 104 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 312 is 3
Notice that 3 = HCF(312,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 795, 624, 312?
Answer: HCF of 795, 624, 312 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 795, 624, 312 using Euclid's Algorithm?
Answer: For arbitrary numbers 795, 624, 312 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
