HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 318, 206 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 509, 318, 206 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 509, 318, 206 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 509, 318, 206 is 1.
HCF(509, 318, 206) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 509, 318, 206 is 1.
Step 1: Since 509 > 318, we apply the division lemma to 509 and 318, to get
509 = 318 x 1 + 191
Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 191 and 318, to get
318 = 191 x 1 + 127
Step 3: We consider the new divisor 191 and the new remainder 127, and apply the division lemma to get
191 = 127 x 1 + 64
We consider the new divisor 127 and the new remainder 64,and apply the division lemma to get
127 = 64 x 1 + 63
We consider the new divisor 64 and the new remainder 63,and apply the division lemma to get
64 = 63 x 1 + 1
We consider the new divisor 63 and the new remainder 1,and apply the division lemma to get
63 = 1 x 63 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 509 and 318 is 1
Notice that 1 = HCF(63,1) = HCF(64,63) = HCF(127,64) = HCF(191,127) = HCF(318,191) = HCF(509,318) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 206 > 1, we apply the division lemma to 206 and 1, to get
206 = 1 x 206 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 206 is 1
Notice that 1 = HCF(206,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 509, 318, 206?
Answer: HCF of 509, 318, 206 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 509, 318, 206 using Euclid's Algorithm?
Answer: For arbitrary numbers 509, 318, 206 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
