HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 219, 420, 164 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 219, 420, 164 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 219, 420, 164 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 219, 420, 164 is 1.

HCF(219, 420, 164) = 1

HCF of 219, 420, 164 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 219, 420, 164 is 1.

Highest Common Factor of 219,420,164 using Euclid's algorithm

Highest Common Factor of 219,420,164 is 1

Step 1: Since 420 > 219, we apply the division lemma to 420 and 219, to get

420 = 219 x 1 + 201

Step 2: Since the reminder 219 ≠ 0, we apply division lemma to 201 and 219, to get

219 = 201 x 1 + 18

Step 3: We consider the new divisor 201 and the new remainder 18, and apply the division lemma to get

201 = 18 x 11 + 3

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

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 219 and 420 is 3

Notice that 3 = HCF(18,3) = HCF(201,18) = HCF(219,201) = HCF(420,219) .

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

Step 1: Since 164 > 3, we apply the division lemma to 164 and 3, to get

164 = 3 x 54 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 164 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(164,3) .
