HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 449, 180 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 718, 449, 180 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 718, 449, 180 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 718, 449, 180 is 1.

HCF(718, 449, 180) = 1

Highest common factor (HCF) of 718, 449, 180 is 1.

Highest Common Factor of 718,449,180 using Euclid's algorithm

Highest Common Factor of 718,449,180 is 1

Step 1: Since 718 > 449, we apply the division lemma to 718 and 449, to get

718 = 449 x 1 + 269

Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 269 and 449, to get

449 = 269 x 1 + 180

Step 3: We consider the new divisor 269 and the new remainder 180, and apply the division lemma to get

269 = 180 x 1 + 89

We consider the new divisor 180 and the new remainder 89,and apply the division lemma to get

180 = 89 x 2 + 2

We consider the new divisor 89 and the new remainder 2,and apply the division lemma to get

89 = 2 x 44 + 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 718 and 449 is 1

Notice that 1 = HCF(2,1) = HCF(89,2) = HCF(180,89) = HCF(269,180) = HCF(449,269) = HCF(718,449) .

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

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

180 = 1 x 180 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 180 is 1

Notice that 1 = HCF(180,1) .
