HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 839 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 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 342, 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 342, 839 is 1.
HCF(342, 839) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 839 is 1.
Step 1: Since 839 > 342, we apply the division lemma to 839 and 342, to get
839 = 342 x 2 + 155
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 155 and 342, to get
342 = 155 x 2 + 32
Step 3: We consider the new divisor 155 and the new remainder 32, and apply the division lemma to get
155 = 32 x 4 + 27
We consider the new divisor 32 and the new remainder 27,and apply the division lemma to get
32 = 27 x 1 + 5
We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get
27 = 5 x 5 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 342 and 839 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(32,27) = HCF(155,32) = HCF(342,155) = HCF(839,342) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 342, 839?
Answer: HCF of 342, 839 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 342, 839 using Euclid's Algorithm?
Answer: For arbitrary numbers 342, 839 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
