HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 950, 578, 209 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 950, 578, 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 950, 578, 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 950, 578, 209 is 1.

HCF(950, 578, 209) = 1

Highest common factor (HCF) of 950, 578, 209 is 1.

Highest Common Factor of 950,578,209 using Euclid's algorithm

Highest Common Factor of 950,578,209 is 1

Step 1: Since 950 > 578, we apply the division lemma to 950 and 578, to get

950 = 578 x 1 + 372

Step 2: Since the reminder 578 ≠ 0, we apply division lemma to 372 and 578, to get

578 = 372 x 1 + 206

Step 3: We consider the new divisor 372 and the new remainder 206, and apply the division lemma to get

372 = 206 x 1 + 166

We consider the new divisor 206 and the new remainder 166,and apply the division lemma to get

206 = 166 x 1 + 40

We consider the new divisor 166 and the new remainder 40,and apply the division lemma to get

166 = 40 x 4 + 6

We consider the new divisor 40 and the new remainder 6,and apply the division lemma to get

40 = 6 x 6 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 950 and 578 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(40,6) = HCF(166,40) = HCF(206,166) = HCF(372,206) = HCF(578,372) = HCF(950,578) .

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

Step 1: Since 209 > 2, we apply the division lemma to 209 and 2, to get

209 = 2 x 104 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 209 is 1

Notice that 1 = HCF(2,1) = HCF(209,2) .
