HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 543, 533 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 543, 533 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 720, 543, 533 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 720, 543, 533 is 1.

HCF(720, 543, 533) = 1

HCF of 720, 543, 533 using Euclid's algorithm

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

Highest common factor (HCF) of 720, 543, 533 is 1.

Highest Common Factor of 720,543,533 using Euclid's algorithm

Highest Common Factor of 720,543,533 is 1

Step 1: Since 720 > 543, we apply the division lemma to 720 and 543, to get

720 = 543 x 1 + 177

Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 177 and 543, to get

543 = 177 x 3 + 12

Step 3: We consider the new divisor 177 and the new remainder 12, and apply the division lemma to get

177 = 12 x 14 + 9

We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get

12 = 9 x 1 + 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 720 and 543 is 3

Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(177,12) = HCF(543,177) = HCF(720,543) .

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

Step 1: Since 533 > 3, we apply the division lemma to 533 and 3, to get

533 = 3 x 177 + 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 533 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(533,3) .
