HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 844, 475, 621 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 844, 475, 621 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 844, 475, 621 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 844, 475, 621 is 1.

HCF(844, 475, 621) = 1

HCF of 844, 475, 621 using Euclid's algorithm

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

Highest common factor (HCF) of 844, 475, 621 is 1.

Highest Common Factor of 844,475,621 using Euclid's algorithm

Highest Common Factor of 844,475,621 is 1

Step 1: Since 844 > 475, we apply the division lemma to 844 and 475, to get

844 = 475 x 1 + 369

Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 369 and 475, to get

475 = 369 x 1 + 106

Step 3: We consider the new divisor 369 and the new remainder 106, and apply the division lemma to get

369 = 106 x 3 + 51

We consider the new divisor 106 and the new remainder 51,and apply the division lemma to get

106 = 51 x 2 + 4

We consider the new divisor 51 and the new remainder 4,and apply the division lemma to get

51 = 4 x 12 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 844 and 475 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(51,4) = HCF(106,51) = HCF(369,106) = HCF(475,369) = HCF(844,475) .

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

Step 1: Since 621 > 1, we apply the division lemma to 621 and 1, to get

621 = 1 x 621 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 621 is 1

Notice that 1 = HCF(621,1) .
