HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 209 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 315, 209 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 315, 209 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 315, 209 is 1.

HCF(315, 209) = 1

HCF of 315, 209 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 315, 209 is 1.

Highest Common Factor of 315,209 using Euclid's algorithm

Highest Common Factor of 315,209 is 1

Step 1: Since 315 > 209, we apply the division lemma to 315 and 209, to get

315 = 209 x 1 + 106

Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 106 and 209, to get

209 = 106 x 1 + 103

Step 3: We consider the new divisor 106 and the new remainder 103, and apply the division lemma to get

106 = 103 x 1 + 3

We consider the new divisor 103 and the new remainder 3,and apply the division lemma to get

103 = 3 x 34 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 315 and 209 is 1

Notice that 1 = HCF(3,1) = HCF(103,3) = HCF(106,103) = HCF(209,106) = HCF(315,209) .
