HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 465, 404 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 180, 465, 404 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 180, 465, 404 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 180, 465, 404 is 1.

HCF(180, 465, 404) = 1

Highest common factor (HCF) of 180, 465, 404 is 1.

Highest Common Factor of 180,465,404 using Euclid's algorithm

Highest Common Factor of 180,465,404 is 1

Step 1: Since 465 > 180, we apply the division lemma to 465 and 180, to get

465 = 180 x 2 + 105

Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 105 and 180, to get

180 = 105 x 1 + 75

Step 3: We consider the new divisor 105 and the new remainder 75, and apply the division lemma to get

105 = 75 x 1 + 30

We consider the new divisor 75 and the new remainder 30,and apply the division lemma to get

75 = 30 x 2 + 15

We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get

30 = 15 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 180 and 465 is 15

Notice that 15 = HCF(30,15) = HCF(75,30) = HCF(105,75) = HCF(180,105) = HCF(465,180) .

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

Step 1: Since 404 > 15, we apply the division lemma to 404 and 15, to get

404 = 15 x 26 + 14

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 14 and 15, to get

15 = 14 x 1 + 1

Step 3: We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 404 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(404,15) .
