HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 377, 449, 15 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 377, 449, 15 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 377, 449, 15 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 377, 449, 15 is 1.

HCF(377, 449, 15) = 1

HCF of 377, 449, 15 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 377, 449, 15 is 1.

Highest Common Factor of 377,449,15 using Euclid's algorithm

Highest Common Factor of 377,449,15 is 1

Step 1: Since 449 > 377, we apply the division lemma to 449 and 377, to get

449 = 377 x 1 + 72

Step 2: Since the reminder 377 ≠ 0, we apply division lemma to 72 and 377, to get

377 = 72 x 5 + 17

Step 3: We consider the new divisor 72 and the new remainder 17, and apply the division lemma to get

72 = 17 x 4 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 377 and 449 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(72,17) = HCF(377,72) = HCF(449,377) .


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

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

15 = 1 x 15 + 0

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

Notice that 1 = HCF(15,1) .
