HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 5815, 1610 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 189, 5815, 1610 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 189, 5815, 1610 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 189, 5815, 1610 is 1.

HCF(189, 5815, 1610) = 1

HCF of 189, 5815, 1610 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 189, 5815, 1610 is 1.

Highest Common Factor of 189,5815,1610 using Euclid's algorithm

Highest Common Factor of 189,5815,1610 is 1

Step 1: Since 5815 > 189, we apply the division lemma to 5815 and 189, to get

5815 = 189 x 30 + 145

Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 145 and 189, to get

189 = 145 x 1 + 44

Step 3: We consider the new divisor 145 and the new remainder 44, and apply the division lemma to get

145 = 44 x 3 + 13

We consider the new divisor 44 and the new remainder 13,and apply the division lemma to get

44 = 13 x 3 + 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 189 and 5815 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(44,13) = HCF(145,44) = HCF(189,145) = HCF(5815,189) .

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

Step 1: Since 1610 > 1, we apply the division lemma to 1610 and 1, to get

1610 = 1 x 1610 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1610 is 1

Notice that 1 = HCF(1610,1) .
