HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3965, 2005 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 3965, 2005 is 5 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 3965, 2005 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 3965, 2005 is 5.

HCF(3965, 2005) = 5

Highest common factor (HCF) of 3965, 2005 is 5.

Highest Common Factor of 3965,2005 using Euclid's algorithm

Highest Common Factor of 3965,2005 is 5

Step 1: Since 3965 > 2005, we apply the division lemma to 3965 and 2005, to get

3965 = 2005 x 1 + 1960

Step 2: Since the reminder 2005 ≠ 0, we apply division lemma to 1960 and 2005, to get

2005 = 1960 x 1 + 45

Step 3: We consider the new divisor 1960 and the new remainder 45, and apply the division lemma to get

1960 = 45 x 43 + 25

We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get

45 = 25 x 1 + 20

We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get

25 = 20 x 1 + 5

We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 3965 and 2005 is 5

Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(1960,45) = HCF(2005,1960) = HCF(3965,2005) .
