HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 385, 214 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 491, 385, 214 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 491, 385, 214 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 491, 385, 214 is 1.

HCF(491, 385, 214) = 1

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

HCF of:

Highest common factor (HCF) of 491, 385, 214 is 1.

Highest Common Factor of 491,385,214 using Euclid's algorithm

Highest Common Factor of 491,385,214 is 1

Step 1: Since 491 > 385, we apply the division lemma to 491 and 385, to get

491 = 385 x 1 + 106

Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 106 and 385, to get

385 = 106 x 3 + 67

Step 3: We consider the new divisor 106 and the new remainder 67, and apply the division lemma to get

106 = 67 x 1 + 39

We consider the new divisor 67 and the new remainder 39,and apply the division lemma to get

67 = 39 x 1 + 28

We consider the new divisor 39 and the new remainder 28,and apply the division lemma to get

39 = 28 x 1 + 11

We consider the new divisor 28 and the new remainder 11,and apply the division lemma to get

28 = 11 x 2 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 385 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(39,28) = HCF(67,39) = HCF(106,67) = HCF(385,106) = HCF(491,385) .

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

Step 1: Since 214 > 1, we apply the division lemma to 214 and 1, to get

214 = 1 x 214 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 214 is 1

Notice that 1 = HCF(214,1) .
