HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 363, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 165, 363, 287 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 165, 363, 287 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 165, 363, 287 is 1.

HCF(165, 363, 287) = 1

HCF of 165, 363, 287 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 165, 363, 287 is 1.

Highest Common Factor of 165,363,287 using Euclid's algorithm

Highest Common Factor of 165,363,287 is 1

Step 1: Since 363 > 165, we apply the division lemma to 363 and 165, to get

363 = 165 x 2 + 33

Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 33 and 165, to get

165 = 33 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 165 and 363 is 33

Notice that 33 = HCF(165,33) = HCF(363,165) .


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

Step 1: Since 287 > 33, we apply the division lemma to 287 and 33, to get

287 = 33 x 8 + 23

Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 23 and 33, to get

33 = 23 x 1 + 10

Step 3: We consider the new divisor 23 and the new remainder 10, and apply the division lemma to get

23 = 10 x 2 + 3

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

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 33 and 287 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(33,23) = HCF(287,33) .
