HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1545, 5161, 97090 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 1545, 5161, 97090 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 1545, 5161, 97090 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 1545, 5161, 97090 is 1.

HCF(1545, 5161, 97090) = 1

HCF of 1545, 5161, 97090 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 1545, 5161, 97090 is 1.

Highest Common Factor of 1545,5161,97090 using Euclid's algorithm

Highest Common Factor of 1545,5161,97090 is 1

Step 1: Since 5161 > 1545, we apply the division lemma to 5161 and 1545, to get

5161 = 1545 x 3 + 526

Step 2: Since the reminder 1545 ≠ 0, we apply division lemma to 526 and 1545, to get

1545 = 526 x 2 + 493

Step 3: We consider the new divisor 526 and the new remainder 493, and apply the division lemma to get

526 = 493 x 1 + 33

We consider the new divisor 493 and the new remainder 33,and apply the division lemma to get

493 = 33 x 14 + 31

We consider the new divisor 33 and the new remainder 31,and apply the division lemma to get

33 = 31 x 1 + 2

We consider the new divisor 31 and the new remainder 2,and apply the division lemma to get

31 = 2 x 15 + 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 1545 and 5161 is 1

Notice that 1 = HCF(2,1) = HCF(31,2) = HCF(33,31) = HCF(493,33) = HCF(526,493) = HCF(1545,526) = HCF(5161,1545) .

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

Step 1: Since 97090 > 1, we apply the division lemma to 97090 and 1, to get

97090 = 1 x 97090 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 97090 is 1

Notice that 1 = HCF(97090,1) .
