HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 856 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 856 is 2 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, 856 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, 856 is 2.
HCF(342, 856) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 856 is 2.
Step 1: Since 856 > 342, we apply the division lemma to 856 and 342, to get
856 = 342 x 2 + 172
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 172 and 342, to get
342 = 172 x 1 + 170
Step 3: We consider the new divisor 172 and the new remainder 170, and apply the division lemma to get
172 = 170 x 1 + 2
We consider the new divisor 170 and the new remainder 2, and apply the division lemma to get
170 = 2 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 342 and 856 is 2
Notice that 2 = HCF(170,2) = HCF(172,170) = HCF(342,172) = HCF(856,342) .
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, 856?
Answer: HCF of 342, 856 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 342, 856 using Euclid's Algorithm?
Answer: For arbitrary numbers 342, 856 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
