HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 476, 638, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 476, 638, 13 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 476, 638, 13 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 476, 638, 13 is 1.
HCF(476, 638, 13) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 476, 638, 13 is 1.
Step 1: Since 638 > 476, we apply the division lemma to 638 and 476, to get
638 = 476 x 1 + 162
Step 2: Since the reminder 476 ≠ 0, we apply division lemma to 162 and 476, to get
476 = 162 x 2 + 152
Step 3: We consider the new divisor 162 and the new remainder 152, and apply the division lemma to get
162 = 152 x 1 + 10
We consider the new divisor 152 and the new remainder 10,and apply the division lemma to get
152 = 10 x 15 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 476 and 638 is 2
Notice that 2 = HCF(10,2) = HCF(152,10) = HCF(162,152) = HCF(476,162) = HCF(638,476) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 2, we apply the division lemma to 13 and 2, to get
13 = 2 x 6 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 13 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 476, 638, 13?
Answer: HCF of 476, 638, 13 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 476, 638, 13 using Euclid's Algorithm?
Answer: For arbitrary numbers 476, 638, 13 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
