HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 854, 911 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 68, 854, 911 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 68, 854, 911 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 68, 854, 911 is 1.

HCF(68, 854, 911) = 1

Highest common factor (HCF) of 68, 854, 911 is 1.

Highest Common Factor of 68,854,911 using Euclid's algorithm

Highest Common Factor of 68,854,911 is 1

Step 1: Since 854 > 68, we apply the division lemma to 854 and 68, to get

854 = 68 x 12 + 38

Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 38 and 68, to get

68 = 38 x 1 + 30

Step 3: We consider the new divisor 38 and the new remainder 30, and apply the division lemma to get

38 = 30 x 1 + 8

We consider the new divisor 30 and the new remainder 8,and apply the division lemma to get

30 = 8 x 3 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 68 and 854 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(30,8) = HCF(38,30) = HCF(68,38) = HCF(854,68) .

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

Step 1: Since 911 > 2, we apply the division lemma to 911 and 2, to get

911 = 2 x 455 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 911 is 1

Notice that 1 = HCF(2,1) = HCF(911,2) .
