HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 988, 628 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 571, 988, 628 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, 988, 628 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, 988, 628 is 1.

HCF(571, 988, 628) = 1

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

HCF of:

Highest common factor (HCF) of 571, 988, 628 is 1.

Highest Common Factor of 571,988,628 using Euclid's algorithm

Highest Common Factor of 571,988,628 is 1

Step 1: Since 988 > 571, we apply the division lemma to 988 and 571, to get

988 = 571 x 1 + 417

Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 417 and 571, to get

571 = 417 x 1 + 154

Step 3: We consider the new divisor 417 and the new remainder 154, and apply the division lemma to get

417 = 154 x 2 + 109

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 988 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(417,154) = HCF(571,417) = HCF(988,571) .

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

Step 1: Since 628 > 1, we apply the division lemma to 628 and 1, to get

628 = 1 x 628 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 628 is 1

Notice that 1 = HCF(628,1) .
