HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 449, 477 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 791, 449, 477 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 791, 449, 477 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 791, 449, 477 is 1.

HCF(791, 449, 477) = 1

Highest common factor (HCF) of 791, 449, 477 is 1.

Highest Common Factor of 791,449,477 using Euclid's algorithm

Highest Common Factor of 791,449,477 is 1

Step 1: Since 791 > 449, we apply the division lemma to 791 and 449, to get

791 = 449 x 1 + 342

Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 342 and 449, to get

449 = 342 x 1 + 107

Step 3: We consider the new divisor 342 and the new remainder 107, and apply the division lemma to get

342 = 107 x 3 + 21

We consider the new divisor 107 and the new remainder 21,and apply the division lemma to get

107 = 21 x 5 + 2

We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get

21 = 2 x 10 + 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 791 and 449 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(107,21) = HCF(342,107) = HCF(449,342) = HCF(791,449) .

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

Step 1: Since 477 > 1, we apply the division lemma to 477 and 1, to get

477 = 1 x 477 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 477 is 1

Notice that 1 = HCF(477,1) .
