HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6917, 6987, 69774 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 6917, 6987, 69774 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 6917, 6987, 69774 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 6917, 6987, 69774 is 1.

HCF(6917, 6987, 69774) = 1

HCF of 6917, 6987, 69774 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 6917, 6987, 69774 is 1.

Highest Common Factor of 6917,6987,69774 using Euclid's algorithm

Highest Common Factor of 6917,6987,69774 is 1

Step 1: Since 6987 > 6917, we apply the division lemma to 6987 and 6917, to get

6987 = 6917 x 1 + 70

Step 2: Since the reminder 6917 ≠ 0, we apply division lemma to 70 and 6917, to get

6917 = 70 x 98 + 57

Step 3: We consider the new divisor 70 and the new remainder 57, and apply the division lemma to get

70 = 57 x 1 + 13

We consider the new divisor 57 and the new remainder 13,and apply the division lemma to get

57 = 13 x 4 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 6917 and 6987 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(57,13) = HCF(70,57) = HCF(6917,70) = HCF(6987,6917) .

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

Step 1: Since 69774 > 1, we apply the division lemma to 69774 and 1, to get

69774 = 1 x 69774 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69774 is 1

Notice that 1 = HCF(69774,1) .
