HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 769, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 449, 769, 847 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 449, 769, 847 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 449, 769, 847 is 1.

HCF(449, 769, 847) = 1

Highest common factor (HCF) of 449, 769, 847 is 1.

Highest Common Factor of 449,769,847 using Euclid's algorithm

Highest Common Factor of 449,769,847 is 1

Step 1: Since 769 > 449, we apply the division lemma to 769 and 449, to get

769 = 449 x 1 + 320

Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 320 and 449, to get

449 = 320 x 1 + 129

Step 3: We consider the new divisor 320 and the new remainder 129, and apply the division lemma to get

320 = 129 x 2 + 62

We consider the new divisor 129 and the new remainder 62,and apply the division lemma to get

129 = 62 x 2 + 5

We consider the new divisor 62 and the new remainder 5,and apply the division lemma to get

62 = 5 x 12 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 449 and 769 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(62,5) = HCF(129,62) = HCF(320,129) = HCF(449,320) = HCF(769,449) .

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

Step 1: Since 847 > 1, we apply the division lemma to 847 and 1, to get

847 = 1 x 847 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 847 is 1

Notice that 1 = HCF(847,1) .
