HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2191, 2405 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 2191, 2405 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 2191, 2405 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 2191, 2405 is 1.

HCF(2191, 2405) = 1

Highest common factor (HCF) of 2191, 2405 is 1.

Highest Common Factor of 2191,2405 using Euclid's algorithm

Highest Common Factor of 2191,2405 is 1

Step 1: Since 2405 > 2191, we apply the division lemma to 2405 and 2191, to get

2405 = 2191 x 1 + 214

Step 2: Since the reminder 2191 ≠ 0, we apply division lemma to 214 and 2191, to get

2191 = 214 x 10 + 51

Step 3: We consider the new divisor 214 and the new remainder 51, and apply the division lemma to get

214 = 51 x 4 + 10

We consider the new divisor 51 and the new remainder 10,and apply the division lemma to get

51 = 10 x 5 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2191 and 2405 is 1

Notice that 1 = HCF(10,1) = HCF(51,10) = HCF(214,51) = HCF(2191,214) = HCF(2405,2191) .
