HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 335, 668 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 509, 335, 668 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, 335, 668 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, 335, 668 is 1.

HCF(509, 335, 668) = 1

Highest common factor (HCF) of 509, 335, 668 is 1.

Highest Common Factor of 509,335,668 using Euclid's algorithm

Highest Common Factor of 509,335,668 is 1

Step 1: Since 509 > 335, we apply the division lemma to 509 and 335, to get

509 = 335 x 1 + 174

Step 2: Since the reminder 335 ≠ 0, we apply division lemma to 174 and 335, to get

335 = 174 x 1 + 161

Step 3: We consider the new divisor 174 and the new remainder 161, and apply the division lemma to get

174 = 161 x 1 + 13

We consider the new divisor 161 and the new remainder 13,and apply the division lemma to get

161 = 13 x 12 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 509 and 335 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(161,13) = HCF(174,161) = HCF(335,174) = HCF(509,335) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 668 > 1, we apply the division lemma to 668 and 1, to get

668 = 1 x 668 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 668 is 1

Notice that 1 = HCF(668,1) .
