HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 261, 506 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 261, 506 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 318, 261, 506 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 318, 261, 506 is 1.

HCF(318, 261, 506) = 1

HCF of 318, 261, 506 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 318, 261, 506 is 1.

Highest Common Factor of 318,261,506 using Euclid's algorithm

Highest Common Factor of 318,261,506 is 1

Step 1: Since 318 > 261, we apply the division lemma to 318 and 261, to get

318 = 261 x 1 + 57

Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 57 and 261, to get

261 = 57 x 4 + 33

Step 3: We consider the new divisor 57 and the new remainder 33, and apply the division lemma to get

57 = 33 x 1 + 24

We consider the new divisor 33 and the new remainder 24,and apply the division lemma to get

33 = 24 x 1 + 9

We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get

24 = 9 x 2 + 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 318 and 261 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(33,24) = HCF(57,33) = HCF(261,57) = HCF(318,261) .

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

Step 1: Since 506 > 3, we apply the division lemma to 506 and 3, to get

506 = 3 x 168 + 2

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

3 = 2 x 1 + 1

Step 3: 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 3 and 506 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(506,3) .
