HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 210, 346 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 644, 210, 346 is 2 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 644, 210, 346 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 644, 210, 346 is 2.

HCF(644, 210, 346) = 2

HCF of 644, 210, 346 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 644, 210, 346 is 2.

Highest Common Factor of 644,210,346 using Euclid's algorithm

Highest Common Factor of 644,210,346 is 2

Step 1: Since 644 > 210, we apply the division lemma to 644 and 210, to get

644 = 210 x 3 + 14

Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 14 and 210, to get

210 = 14 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 644 and 210 is 14

Notice that 14 = HCF(210,14) = HCF(644,210) .


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

Step 1: Since 346 > 14, we apply the division lemma to 346 and 14, to get

346 = 14 x 24 + 10

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 10 and 14, to get

14 = 10 x 1 + 4

Step 3: We consider the new divisor 10 and the new remainder 4, and apply the division lemma to get

10 = 4 x 2 + 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 14 and 346 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(346,14) .
