HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 329, 449, 777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 329, 449, 777 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 329, 449, 777 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 329, 449, 777 is 1.

HCF(329, 449, 777) = 1

Highest common factor (HCF) of 329, 449, 777 is 1.

Highest Common Factor of 329,449,777 using Euclid's algorithm

Highest Common Factor of 329,449,777 is 1

Step 1: Since 449 > 329, we apply the division lemma to 449 and 329, to get

449 = 329 x 1 + 120

Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 120 and 329, to get

329 = 120 x 2 + 89

Step 3: We consider the new divisor 120 and the new remainder 89, and apply the division lemma to get

120 = 89 x 1 + 31

We consider the new divisor 89 and the new remainder 31,and apply the division lemma to get

89 = 31 x 2 + 27

We consider the new divisor 31 and the new remainder 27,and apply the division lemma to get

31 = 27 x 1 + 4

We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get

27 = 4 x 6 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 329 and 449 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) = HCF(89,31) = HCF(120,89) = HCF(329,120) = HCF(449,329) .

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

Step 1: Since 777 > 1, we apply the division lemma to 777 and 1, to get

777 = 1 x 777 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 777 is 1

Notice that 1 = HCF(777,1) .
