HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 347, 828 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 421, 347, 828 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, 347, 828 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, 347, 828 is 1.

HCF(421, 347, 828) = 1

Highest common factor (HCF) of 421, 347, 828 is 1.

Highest Common Factor of 421,347,828 using Euclid's algorithm

Highest Common Factor of 421,347,828 is 1

Step 1: Since 421 > 347, we apply the division lemma to 421 and 347, to get

421 = 347 x 1 + 74

Step 2: Since the reminder 347 ≠ 0, we apply division lemma to 74 and 347, to get

347 = 74 x 4 + 51

Step 3: We consider the new divisor 74 and the new remainder 51, and apply the division lemma to get

74 = 51 x 1 + 23

We consider the new divisor 51 and the new remainder 23,and apply the division lemma to get

51 = 23 x 2 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 347 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(51,23) = HCF(74,51) = HCF(347,74) = HCF(421,347) .

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

Step 1: Since 828 > 1, we apply the division lemma to 828 and 1, to get

828 = 1 x 828 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 828 is 1

Notice that 1 = HCF(828,1) .
