HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 313, 795, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 313, 795, 255 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 313, 795, 255 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 313, 795, 255 is 1.
HCF(313, 795, 255) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 313, 795, 255 is 1.
Step 1: Since 795 > 313, we apply the division lemma to 795 and 313, to get
795 = 313 x 2 + 169
Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 169 and 313, to get
313 = 169 x 1 + 144
Step 3: We consider the new divisor 169 and the new remainder 144, and apply the division lemma to get
169 = 144 x 1 + 25
We consider the new divisor 144 and the new remainder 25,and apply the division lemma to get
144 = 25 x 5 + 19
We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get
25 = 19 x 1 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 313 and 795 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(144,25) = HCF(169,144) = HCF(313,169) = HCF(795,313) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get
255 = 1 x 255 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1
Notice that 1 = HCF(255,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 313, 795, 255?
Answer: HCF of 313, 795, 255 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 313, 795, 255 using Euclid's Algorithm?
Answer: For arbitrary numbers 313, 795, 255 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
