HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 535, 839 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 535, 839 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 380, 535, 839 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 380, 535, 839 is 1.
HCF(380, 535, 839) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 535, 839 is 1.
Step 1: Since 535 > 380, we apply the division lemma to 535 and 380, to get
535 = 380 x 1 + 155
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 155 and 380, to get
380 = 155 x 2 + 70
Step 3: We consider the new divisor 155 and the new remainder 70, and apply the division lemma to get
155 = 70 x 2 + 15
We consider the new divisor 70 and the new remainder 15,and apply the division lemma to get
70 = 15 x 4 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 380 and 535 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(70,15) = HCF(155,70) = HCF(380,155) = HCF(535,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 839 > 5, we apply the division lemma to 839 and 5, to get
839 = 5 x 167 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 839 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(839,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 380, 535, 839?
Answer: HCF of 380, 535, 839 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 380, 535, 839 using Euclid's Algorithm?
