HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 740, 391, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 740, 391, 571 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 740, 391, 571 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 740, 391, 571 is 1.

HCF(740, 391, 571) = 1

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

HCF of:

Highest common factor (HCF) of 740, 391, 571 is 1.

Highest Common Factor of 740,391,571 using Euclid's algorithm

Highest Common Factor of 740,391,571 is 1

Step 1: Since 740 > 391, we apply the division lemma to 740 and 391, to get

740 = 391 x 1 + 349

Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 349 and 391, to get

391 = 349 x 1 + 42

Step 3: We consider the new divisor 349 and the new remainder 42, and apply the division lemma to get

349 = 42 x 8 + 13

We consider the new divisor 42 and the new remainder 13,and apply the division lemma to get

42 = 13 x 3 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 740 and 391 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(42,13) = HCF(349,42) = HCF(391,349) = HCF(740,391) .

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

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

571 = 1 x 571 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 571 is 1

Notice that 1 = HCF(571,1) .
