HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 403, 788, 734 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 403, 788, 734 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 403, 788, 734 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 403, 788, 734 is 1.

HCF(403, 788, 734) = 1

Highest common factor (HCF) of 403, 788, 734 is 1.

Highest Common Factor of 403,788,734 using Euclid's algorithm

Highest Common Factor of 403,788,734 is 1

Step 1: Since 788 > 403, we apply the division lemma to 788 and 403, to get

788 = 403 x 1 + 385

Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 385 and 403, to get

403 = 385 x 1 + 18

Step 3: We consider the new divisor 385 and the new remainder 18, and apply the division lemma to get

385 = 18 x 21 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 403 and 788 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(385,18) = HCF(403,385) = HCF(788,403) .

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

Step 1: Since 734 > 1, we apply the division lemma to 734 and 1, to get

734 = 1 x 734 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 734 is 1

Notice that 1 = HCF(734,1) .
