HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 681, 488 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 681, 488 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, 681, 488 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, 681, 488 is 1.

HCF(768, 681, 488) = 1

Highest common factor (HCF) of 768, 681, 488 is 1.

Highest Common Factor of 768,681,488 using Euclid's algorithm

Highest Common Factor of 768,681,488 is 1

Step 1: Since 768 > 681, we apply the division lemma to 768 and 681, to get

768 = 681 x 1 + 87

Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 87 and 681, to get

681 = 87 x 7 + 72

Step 3: We consider the new divisor 87 and the new remainder 72, and apply the division lemma to get

87 = 72 x 1 + 15

We consider the new divisor 72 and the new remainder 15,and apply the division lemma to get

72 = 15 x 4 + 12

We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get

15 = 12 x 1 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 768 and 681 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(72,15) = HCF(87,72) = HCF(681,87) = HCF(768,681) .

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

Step 1: Since 488 > 3, we apply the division lemma to 488 and 3, to get

488 = 3 x 162 + 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 488 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(488,3) .
