HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 340, 906, 397 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 340, 906, 397 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 340, 906, 397 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 340, 906, 397 is 1.
HCF(340, 906, 397) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 340, 906, 397 is 1.
Step 1: Since 906 > 340, we apply the division lemma to 906 and 340, to get
906 = 340 x 2 + 226
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 226 and 340, to get
340 = 226 x 1 + 114
Step 3: We consider the new divisor 226 and the new remainder 114, and apply the division lemma to get
226 = 114 x 1 + 112
We consider the new divisor 114 and the new remainder 112,and apply the division lemma to get
114 = 112 x 1 + 2
We consider the new divisor 112 and the new remainder 2,and apply the division lemma to get
112 = 2 x 56 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 340 and 906 is 2
Notice that 2 = HCF(112,2) = HCF(114,112) = HCF(226,114) = HCF(340,226) = HCF(906,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 397 > 2, we apply the division lemma to 397 and 2, to get
397 = 2 x 198 + 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 397 is 1
Notice that 1 = HCF(2,1) = HCF(397,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 340, 906, 397?
Answer: HCF of 340, 906, 397 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 340, 906, 397 using Euclid's Algorithm?
Answer: For arbitrary numbers 340, 906, 397 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
