HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 481 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 768, 481 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 768, 481 is 1.

HCF(768, 481) = 1

Highest common factor (HCF) of 768, 481 is 1.

Highest Common Factor of 768,481 using Euclid's algorithm

Highest Common Factor of 768,481 is 1

Step 1: Since 768 > 481, we apply the division lemma to 768 and 481, to get

768 = 481 x 1 + 287

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 287 and 481, to get

481 = 287 x 1 + 194

Step 3: We consider the new divisor 287 and the new remainder 194, and apply the division lemma to get

287 = 194 x 1 + 93

We consider the new divisor 194 and the new remainder 93,and apply the division lemma to get

194 = 93 x 2 + 8

We consider the new divisor 93 and the new remainder 8,and apply the division lemma to get

93 = 8 x 11 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 768 and 481 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(93,8) = HCF(194,93) = HCF(287,194) = HCF(481,287) = HCF(768,481) .
