HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 609, 217 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 380, 609, 217 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 380, 609, 217 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 380, 609, 217 is 1.

HCF(380, 609, 217) = 1

HCF of 380, 609, 217 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 380, 609, 217 is 1.

Highest Common Factor of 380,609,217 using Euclid's algorithm

Highest Common Factor of 380,609,217 is 1

Step 1: Since 609 > 380, we apply the division lemma to 609 and 380, to get

609 = 380 x 1 + 229

Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 229 and 380, to get

380 = 229 x 1 + 151

Step 3: We consider the new divisor 229 and the new remainder 151, and apply the division lemma to get

229 = 151 x 1 + 78

We consider the new divisor 151 and the new remainder 78,and apply the division lemma to get

151 = 78 x 1 + 73

We consider the new divisor 78 and the new remainder 73,and apply the division lemma to get

78 = 73 x 1 + 5

We consider the new divisor 73 and the new remainder 5,and apply the division lemma to get

73 = 5 x 14 + 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 380 and 609 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(73,5) = HCF(78,73) = HCF(151,78) = HCF(229,151) = HCF(380,229) = HCF(609,380) .

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

Step 1: Since 217 > 1, we apply the division lemma to 217 and 1, to get

217 = 1 x 217 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 217 is 1

Notice that 1 = HCF(217,1) .
