HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 767, 473, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 767, 473, 729 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 767, 473, 729 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 767, 473, 729 is 1.

HCF(767, 473, 729) = 1

Highest common factor (HCF) of 767, 473, 729 is 1.

Highest Common Factor of 767,473,729 using Euclid's algorithm

Highest Common Factor of 767,473,729 is 1

Step 1: Since 767 > 473, we apply the division lemma to 767 and 473, to get

767 = 473 x 1 + 294

Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 294 and 473, to get

473 = 294 x 1 + 179

Step 3: We consider the new divisor 294 and the new remainder 179, and apply the division lemma to get

294 = 179 x 1 + 115

We consider the new divisor 179 and the new remainder 115,and apply the division lemma to get

179 = 115 x 1 + 64

We consider the new divisor 115 and the new remainder 64,and apply the division lemma to get

115 = 64 x 1 + 51

We consider the new divisor 64 and the new remainder 51,and apply the division lemma to get

64 = 51 x 1 + 13

We consider the new divisor 51 and the new remainder 13,and apply the division lemma to get

51 = 13 x 3 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 767 and 473 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(51,13) = HCF(64,51) = HCF(115,64) = HCF(179,115) = HCF(294,179) = HCF(473,294) = HCF(767,473) .

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

Step 1: Since 729 > 1, we apply the division lemma to 729 and 1, to get

729 = 1 x 729 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1

Notice that 1 = HCF(729,1) .
