HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 125, 812 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 321, 125, 812 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 321, 125, 812 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 321, 125, 812 is 1.

HCF(321, 125, 812) = 1

Highest common factor (HCF) of 321, 125, 812 is 1.

Highest Common Factor of 321,125,812 using Euclid's algorithm

Highest Common Factor of 321,125,812 is 1

Step 1: Since 321 > 125, we apply the division lemma to 321 and 125, to get

321 = 125 x 2 + 71

Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 71 and 125, to get

125 = 71 x 1 + 54

Step 3: We consider the new divisor 71 and the new remainder 54, and apply the division lemma to get

71 = 54 x 1 + 17

We consider the new divisor 54 and the new remainder 17,and apply the division lemma to get

54 = 17 x 3 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 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 321 and 125 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(54,17) = HCF(71,54) = HCF(125,71) = HCF(321,125) .

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

Step 1: Since 812 > 1, we apply the division lemma to 812 and 1, to get

812 = 1 x 812 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 812 is 1

Notice that 1 = HCF(812,1) .
