HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 734, 263, 721 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 734, 263, 721 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 734, 263, 721 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 734, 263, 721 is 1.

HCF(734, 263, 721) = 1

HCF of 734, 263, 721 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 734, 263, 721 is 1.

Highest Common Factor of 734,263,721 using Euclid's algorithm

Highest Common Factor of 734,263,721 is 1

Step 1: Since 734 > 263, we apply the division lemma to 734 and 263, to get

734 = 263 x 2 + 208

Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 208 and 263, to get

263 = 208 x 1 + 55

Step 3: We consider the new divisor 208 and the new remainder 55, and apply the division lemma to get

208 = 55 x 3 + 43

We consider the new divisor 55 and the new remainder 43,and apply the division lemma to get

55 = 43 x 1 + 12

We consider the new divisor 43 and the new remainder 12,and apply the division lemma to get

43 = 12 x 3 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 734 and 263 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(43,12) = HCF(55,43) = HCF(208,55) = HCF(263,208) = HCF(734,263) .

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

Step 1: Since 721 > 1, we apply the division lemma to 721 and 1, to get

721 = 1 x 721 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 721 is 1

Notice that 1 = HCF(721,1) .
