HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 234, 209, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 234, 209, 390 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 234, 209, 390 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 234, 209, 390 is 1.
HCF(234, 209, 390) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 234, 209, 390 is 1.
Step 1: Since 234 > 209, we apply the division lemma to 234 and 209, to get
234 = 209 x 1 + 25
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 25 and 209, to get
209 = 25 x 8 + 9
Step 3: We consider the new divisor 25 and the new remainder 9, and apply the division lemma to get
25 = 9 x 2 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 234 and 209 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(25,9) = HCF(209,25) = HCF(234,209) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get
390 = 1 x 390 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1
Notice that 1 = HCF(390,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 234, 209, 390?
Answer: HCF of 234, 209, 390 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 234, 209, 390 using Euclid's Algorithm?
Answer: For arbitrary numbers 234, 209, 390 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
