HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 763, 418, 318 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 763, 418, 318 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 763, 418, 318 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 763, 418, 318 is 1.

HCF(763, 418, 318) = 1

Highest common factor (HCF) of 763, 418, 318 is 1.

Highest Common Factor of 763,418,318 using Euclid's algorithm

Highest Common Factor of 763,418,318 is 1

Step 1: Since 763 > 418, we apply the division lemma to 763 and 418, to get

763 = 418 x 1 + 345

Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 345 and 418, to get

418 = 345 x 1 + 73

Step 3: We consider the new divisor 345 and the new remainder 73, and apply the division lemma to get

345 = 73 x 4 + 53

We consider the new divisor 73 and the new remainder 53,and apply the division lemma to get

73 = 53 x 1 + 20

We consider the new divisor 53 and the new remainder 20,and apply the division lemma to get

53 = 20 x 2 + 13

We consider the new divisor 20 and the new remainder 13,and apply the division lemma to get

20 = 13 x 1 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 763 and 418 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(53,20) = HCF(73,53) = HCF(345,73) = HCF(418,345) = HCF(763,418) .

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

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

318 = 1 x 318 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1

Notice that 1 = HCF(318,1) .
