HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 4241, 4605 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 165, 4241, 4605 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, 4241, 4605 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, 4241, 4605 is 1.

HCF(165, 4241, 4605) = 1

Highest common factor (HCF) of 165, 4241, 4605 is 1.

Highest Common Factor of 165,4241,4605 using Euclid's algorithm

Highest Common Factor of 165,4241,4605 is 1

Step 1: Since 4241 > 165, we apply the division lemma to 4241 and 165, to get

4241 = 165 x 25 + 116

Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 116 and 165, to get

165 = 116 x 1 + 49

Step 3: We consider the new divisor 116 and the new remainder 49, and apply the division lemma to get

116 = 49 x 2 + 18

We consider the new divisor 49 and the new remainder 18,and apply the division lemma to get

49 = 18 x 2 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

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 165 and 4241 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(49,18) = HCF(116,49) = HCF(165,116) = HCF(4241,165) .

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

Step 1: Since 4605 > 1, we apply the division lemma to 4605 and 1, to get

4605 = 1 x 4605 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4605 is 1

Notice that 1 = HCF(4605,1) .
