HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1081, 3645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 1081, 3645 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 1081, 3645 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 1081, 3645 is 1.

HCF(1081, 3645) = 1

Highest common factor (HCF) of 1081, 3645 is 1.

Highest Common Factor of 1081,3645 using Euclid's algorithm

Highest Common Factor of 1081,3645 is 1

Step 1: Since 3645 > 1081, we apply the division lemma to 3645 and 1081, to get

3645 = 1081 x 3 + 402

Step 2: Since the reminder 1081 ≠ 0, we apply division lemma to 402 and 1081, to get

1081 = 402 x 2 + 277

Step 3: We consider the new divisor 402 and the new remainder 277, and apply the division lemma to get

402 = 277 x 1 + 125

We consider the new divisor 277 and the new remainder 125,and apply the division lemma to get

277 = 125 x 2 + 27

We consider the new divisor 125 and the new remainder 27,and apply the division lemma to get

125 = 27 x 4 + 17

We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get

27 = 17 x 1 + 10

We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get

17 = 10 x 1 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 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 1081 and 3645 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(125,27) = HCF(277,125) = HCF(402,277) = HCF(1081,402) = HCF(3645,1081) .
