HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 421, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 571, 421, 673 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, 421, 673 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, 421, 673 is 1.

HCF(571, 421, 673) = 1

Highest Common Factor of 571,421,673 using Euclid's algorithm

Highest Common Factor of 571,421,673 is 1

Step 1: Since 571 > 421, we apply the division lemma to 571 and 421, to get

571 = 421 x 1 + 150

Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 150 and 421, to get

421 = 150 x 2 + 121

Step 3: We consider the new divisor 150 and the new remainder 121, and apply the division lemma to get

150 = 121 x 1 + 29

We consider the new divisor 121 and the new remainder 29,and apply the division lemma to get

121 = 29 x 4 + 5

We consider the new divisor 29 and the new remainder 5,and apply the division lemma to get

29 = 5 x 5 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 421 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) = HCF(121,29) = HCF(150,121) = HCF(421,150) = HCF(571,421) .

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

Step 1: Since 673 > 1, we apply the division lemma to 673 and 1, to get

673 = 1 x 673 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 673 is 1

Notice that 1 = HCF(673,1) .
