HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 768 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 471, 768 is 3 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 471, 768 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 471, 768 is 3.

HCF(471, 768) = 3

Highest Common Factor of 471,768 using Euclid's algorithm

Highest Common Factor of 471,768 is 3

Step 1: Since 768 > 471, we apply the division lemma to 768 and 471, to get

768 = 471 x 1 + 297

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 297 and 471, to get

471 = 297 x 1 + 174

Step 3: We consider the new divisor 297 and the new remainder 174, and apply the division lemma to get

297 = 174 x 1 + 123

We consider the new divisor 174 and the new remainder 123,and apply the division lemma to get

174 = 123 x 1 + 51

We consider the new divisor 123 and the new remainder 51,and apply the division lemma to get

123 = 51 x 2 + 21

We consider the new divisor 51 and the new remainder 21,and apply the division lemma to get

51 = 21 x 2 + 9

We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get

21 = 9 x 2 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 471 and 768 is 3

Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(51,21) = HCF(123,51) = HCF(174,123) = HCF(297,174) = HCF(471,297) = HCF(768,471) .
