HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 725, 524 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 571, 725, 524 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 571, 725, 524 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 571, 725, 524 is 1.

HCF(571, 725, 524) = 1

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

HCF of:

Highest common factor (HCF) of 571, 725, 524 is 1.

Highest Common Factor of 571,725,524 using Euclid's algorithm

Highest Common Factor of 571,725,524 is 1

Step 1: Since 725 > 571, we apply the division lemma to 725 and 571, to get

725 = 571 x 1 + 154

Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 154 and 571, to get

571 = 154 x 3 + 109

Step 3: We consider the new divisor 154 and the new remainder 109, and apply the division lemma to get

154 = 109 x 1 + 45

We consider the new divisor 109 and the new remainder 45,and apply the division lemma to get

109 = 45 x 2 + 19

We consider the new divisor 45 and the new remainder 19,and apply the division lemma to get

45 = 19 x 2 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 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 571 and 725 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(45,19) = HCF(109,45) = HCF(154,109) = HCF(571,154) = HCF(725,571) .

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

Step 1: Since 524 > 1, we apply the division lemma to 524 and 1, to get

524 = 1 x 524 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 524 is 1

Notice that 1 = HCF(524,1) .
