HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 994, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 571, 994, 857 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, 994, 857 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, 994, 857 is 1.

HCF(571, 994, 857) = 1

HCF of 571, 994, 857 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 571, 994, 857 is 1.

Highest Common Factor of 571,994,857 using Euclid's algorithm

Highest Common Factor of 571,994,857 is 1

Step 1: Since 994 > 571, we apply the division lemma to 994 and 571, to get

994 = 571 x 1 + 423

Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 423 and 571, to get

571 = 423 x 1 + 148

Step 3: We consider the new divisor 423 and the new remainder 148, and apply the division lemma to get

423 = 148 x 2 + 127

We consider the new divisor 148 and the new remainder 127,and apply the division lemma to get

148 = 127 x 1 + 21

We consider the new divisor 127 and the new remainder 21,and apply the division lemma to get

127 = 21 x 6 + 1

We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get

21 = 1 x 21 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 994 is 1

Notice that 1 = HCF(21,1) = HCF(127,21) = HCF(148,127) = HCF(423,148) = HCF(571,423) = HCF(994,571) .

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

Step 1: Since 857 > 1, we apply the division lemma to 857 and 1, to get

857 = 1 x 857 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 857 is 1

Notice that 1 = HCF(857,1) .
