HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 235, 515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 235, 515 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 378, 235, 515 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 378, 235, 515 is 1.
HCF(378, 235, 515) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 378, 235, 515 is 1.
Step 1: Since 378 > 235, we apply the division lemma to 378 and 235, to get
378 = 235 x 1 + 143
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 143 and 235, to get
235 = 143 x 1 + 92
Step 3: We consider the new divisor 143 and the new remainder 92, and apply the division lemma to get
143 = 92 x 1 + 51
We consider the new divisor 92 and the new remainder 51,and apply the division lemma to get
92 = 51 x 1 + 41
We consider the new divisor 51 and the new remainder 41,and apply the division lemma to get
51 = 41 x 1 + 10
We consider the new divisor 41 and the new remainder 10,and apply the division lemma to get
41 = 10 x 4 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 378 and 235 is 1
Notice that 1 = HCF(10,1) = HCF(41,10) = HCF(51,41) = HCF(92,51) = HCF(143,92) = HCF(235,143) = HCF(378,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 515 > 1, we apply the division lemma to 515 and 1, to get
515 = 1 x 515 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 515 is 1
Notice that 1 = HCF(515,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 378, 235, 515?
Answer: HCF of 378, 235, 515 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 378, 235, 515 using Euclid's Algorithm?
Answer: For arbitrary numbers 378, 235, 515 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
