HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 342, 531 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 209, 342, 531 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 209, 342, 531 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 209, 342, 531 is 1.

HCF(209, 342, 531) = 1

Highest common factor (HCF) of 209, 342, 531 is 1.

Highest Common Factor of 209,342,531 using Euclid's algorithm

Highest Common Factor of 209,342,531 is 1

Step 1: Since 342 > 209, we apply the division lemma to 342 and 209, to get

342 = 209 x 1 + 133

Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 133 and 209, to get

209 = 133 x 1 + 76

Step 3: We consider the new divisor 133 and the new remainder 76, and apply the division lemma to get

133 = 76 x 1 + 57

We consider the new divisor 76 and the new remainder 57,and apply the division lemma to get

76 = 57 x 1 + 19

We consider the new divisor 57 and the new remainder 19,and apply the division lemma to get

57 = 19 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 209 and 342 is 19

Notice that 19 = HCF(57,19) = HCF(76,57) = HCF(133,76) = HCF(209,133) = HCF(342,209) .

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

Step 1: Since 531 > 19, we apply the division lemma to 531 and 19, to get

531 = 19 x 27 + 18

Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 18 and 19, to get

19 = 18 x 1 + 1

Step 3: We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 531 is 1

Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(531,19) .
