HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 441, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 677, 441, 76 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 677, 441, 76 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 677, 441, 76 is 1.

HCF(677, 441, 76) = 1

Highest common factor (HCF) of 677, 441, 76 is 1.

Highest Common Factor of 677,441,76 using Euclid's algorithm

Highest Common Factor of 677,441,76 is 1

Step 1: Since 677 > 441, we apply the division lemma to 677 and 441, to get

677 = 441 x 1 + 236

Step 2: Since the reminder 441 ≠ 0, we apply division lemma to 236 and 441, to get

441 = 236 x 1 + 205

Step 3: We consider the new divisor 236 and the new remainder 205, and apply the division lemma to get

236 = 205 x 1 + 31

We consider the new divisor 205 and the new remainder 31,and apply the division lemma to get

205 = 31 x 6 + 19

We consider the new divisor 31 and the new remainder 19,and apply the division lemma to get

31 = 19 x 1 + 12

We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 677 and 441 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(31,19) = HCF(205,31) = HCF(236,205) = HCF(441,236) = HCF(677,441) .

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

Step 1: Since 76 > 1, we apply the division lemma to 76 and 1, to get

76 = 1 x 76 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76 is 1

Notice that 1 = HCF(76,1) .
