HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 443, 644, 359 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 443, 644, 359 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 443, 644, 359 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 443, 644, 359 is 1.

HCF(443, 644, 359) = 1

HCF of 443, 644, 359 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 443, 644, 359 is 1.

Highest Common Factor of 443,644,359 using Euclid's algorithm

Highest Common Factor of 443,644,359 is 1

Step 1: Since 644 > 443, we apply the division lemma to 644 and 443, to get

644 = 443 x 1 + 201

Step 2: Since the reminder 443 ≠ 0, we apply division lemma to 201 and 443, to get

443 = 201 x 2 + 41

Step 3: We consider the new divisor 201 and the new remainder 41, and apply the division lemma to get

201 = 41 x 4 + 37

We consider the new divisor 41 and the new remainder 37,and apply the division lemma to get

41 = 37 x 1 + 4

We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get

37 = 4 x 9 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 443 and 644 is 1

Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(41,37) = HCF(201,41) = HCF(443,201) = HCF(644,443) .

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

Step 1: Since 359 > 1, we apply the division lemma to 359 and 1, to get

359 = 1 x 359 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 359 is 1

Notice that 1 = HCF(359,1) .
