HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 591, 705, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 591, 705, 743 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 591, 705, 743 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 591, 705, 743 is 1.

HCF(591, 705, 743) = 1

HCF of 591, 705, 743 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 591, 705, 743 is 1.

Highest Common Factor of 591,705,743 using Euclid's algorithm

Highest Common Factor of 591,705,743 is 1

Step 1: Since 705 > 591, we apply the division lemma to 705 and 591, to get

705 = 591 x 1 + 114

Step 2: Since the reminder 591 ≠ 0, we apply division lemma to 114 and 591, to get

591 = 114 x 5 + 21

Step 3: We consider the new divisor 114 and the new remainder 21, and apply the division lemma to get

114 = 21 x 5 + 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 591 and 705 is 3

Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(114,21) = HCF(591,114) = HCF(705,591) .

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

Step 1: Since 743 > 3, we apply the division lemma to 743 and 3, to get

743 = 3 x 247 + 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 743 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(743,3) .
