HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 687, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 741, 687, 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 741, 687, 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 741, 687, 847 is 1.

HCF(741, 687, 847) = 1

Highest common factor (HCF) of 741, 687, 847 is 1.

Highest Common Factor of 741,687,847 using Euclid's algorithm

Highest Common Factor of 741,687,847 is 1

Step 1: Since 741 > 687, we apply the division lemma to 741 and 687, to get

741 = 687 x 1 + 54

Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 54 and 687, to get

687 = 54 x 12 + 39

Step 3: We consider the new divisor 54 and the new remainder 39, and apply the division lemma to get

54 = 39 x 1 + 15

We consider the new divisor 39 and the new remainder 15,and apply the division lemma to get

39 = 15 x 2 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 741 and 687 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(39,15) = HCF(54,39) = HCF(687,54) = HCF(741,687) .

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

Step 1: Since 847 > 3, we apply the division lemma to 847 and 3, to get

847 = 3 x 282 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 847 is 1

Notice that 1 = HCF(3,1) = HCF(847,3) .
