HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 648, 911 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 386, 648, 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 386, 648, 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 386, 648, 911 is 1.

HCF(386, 648, 911) = 1

Highest Common Factor of 386,648,911 using Euclid's algorithm

Highest Common Factor of 386,648,911 is 1

Step 1: Since 648 > 386, we apply the division lemma to 648 and 386, to get

648 = 386 x 1 + 262

Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 262 and 386, to get

386 = 262 x 1 + 124

Step 3: We consider the new divisor 262 and the new remainder 124, and apply the division lemma to get

262 = 124 x 2 + 14

We consider the new divisor 124 and the new remainder 14,and apply the division lemma to get

124 = 14 x 8 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 386 and 648 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(124,14) = HCF(262,124) = HCF(386,262) = HCF(648,386) .

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) .
