HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 313, 484, 667 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 313, 484, 667 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, 484, 667 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, 484, 667 is 1.
HCF(313, 484, 667) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 313, 484, 667 is 1.
Step 1: Since 484 > 313, we apply the division lemma to 484 and 313, to get
484 = 313 x 1 + 171
Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 171 and 313, to get
313 = 171 x 1 + 142
Step 3: We consider the new divisor 171 and the new remainder 142, and apply the division lemma to get
171 = 142 x 1 + 29
We consider the new divisor 142 and the new remainder 29,and apply the division lemma to get
142 = 29 x 4 + 26
We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get
29 = 26 x 1 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 313 and 484 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(142,29) = HCF(171,142) = HCF(313,171) = HCF(484,313) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 667 > 1, we apply the division lemma to 667 and 1, to get
667 = 1 x 667 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 667 is 1
Notice that 1 = HCF(667,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 313, 484, 667?
Answer: HCF of 313, 484, 667 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 313, 484, 667 using Euclid's Algorithm?
Answer: For arbitrary numbers 313, 484, 667 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
