HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 573, 721, 384 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 573, 721, 384 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 573, 721, 384 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 573, 721, 384 is 1.

HCF(573, 721, 384) = 1

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

HCF of:

Highest common factor (HCF) of 573, 721, 384 is 1.

Highest Common Factor of 573,721,384 using Euclid's algorithm

Highest Common Factor of 573,721,384 is 1

Step 1: Since 721 > 573, we apply the division lemma to 721 and 573, to get

721 = 573 x 1 + 148

Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 148 and 573, to get

573 = 148 x 3 + 129

Step 3: We consider the new divisor 148 and the new remainder 129, and apply the division lemma to get

148 = 129 x 1 + 19

We consider the new divisor 129 and the new remainder 19,and apply the division lemma to get

129 = 19 x 6 + 15

We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get

19 = 15 x 1 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 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 573 and 721 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(129,19) = HCF(148,129) = HCF(573,148) = HCF(721,573) .

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

Step 1: Since 384 > 1, we apply the division lemma to 384 and 1, to get

384 = 1 x 384 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 384 is 1

Notice that 1 = HCF(384,1) .
