HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 891, 950 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 421, 891, 950 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 421, 891, 950 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 421, 891, 950 is 1.

HCF(421, 891, 950) = 1

HCF of 421, 891, 950 using Euclid's algorithm

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

Highest common factor (HCF) of 421, 891, 950 is 1.

Highest Common Factor of 421,891,950 using Euclid's algorithm

Highest Common Factor of 421,891,950 is 1

Step 1: Since 891 > 421, we apply the division lemma to 891 and 421, to get

891 = 421 x 2 + 49

Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 49 and 421, to get

421 = 49 x 8 + 29

Step 3: We consider the new divisor 49 and the new remainder 29, and apply the division lemma to get

49 = 29 x 1 + 20

We consider the new divisor 29 and the new remainder 20,and apply the division lemma to get

29 = 20 x 1 + 9

We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get

20 = 9 x 2 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 421 and 891 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(29,20) = HCF(49,29) = HCF(421,49) = HCF(891,421) .

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

Step 1: Since 950 > 1, we apply the division lemma to 950 and 1, to get

950 = 1 x 950 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 950 is 1

Notice that 1 = HCF(950,1) .
