HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 412, 186 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 644, 412, 186 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, 412, 186 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, 412, 186 is 2.

HCF(644, 412, 186) = 2

Highest Common Factor of 644,412,186 using Euclid's algorithm

Highest Common Factor of 644,412,186 is 2

Step 1: Since 644 > 412, we apply the division lemma to 644 and 412, to get

644 = 412 x 1 + 232

Step 2: Since the reminder 412 ≠ 0, we apply division lemma to 232 and 412, to get

412 = 232 x 1 + 180

Step 3: We consider the new divisor 232 and the new remainder 180, and apply the division lemma to get

232 = 180 x 1 + 52

We consider the new divisor 180 and the new remainder 52,and apply the division lemma to get

180 = 52 x 3 + 24

We consider the new divisor 52 and the new remainder 24,and apply the division lemma to get

52 = 24 x 2 + 4

We consider the new divisor 24 and the new remainder 4,and apply the division lemma to get

24 = 4 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 644 and 412 is 4

Notice that 4 = HCF(24,4) = HCF(52,24) = HCF(180,52) = HCF(232,180) = HCF(412,232) = HCF(644,412) .

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

Step 1: Since 186 > 4, we apply the division lemma to 186 and 4, to get

186 = 4 x 46 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 186 is 2

Notice that 2 = HCF(4,2) = HCF(186,4) .
