HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 556, 345 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 810, 556, 345 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 810, 556, 345 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 810, 556, 345 is 1.

HCF(810, 556, 345) = 1

Highest common factor (HCF) of 810, 556, 345 is 1.

Highest Common Factor of 810,556,345 using Euclid's algorithm

Highest Common Factor of 810,556,345 is 1

Step 1: Since 810 > 556, we apply the division lemma to 810 and 556, to get

810 = 556 x 1 + 254

Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 254 and 556, to get

556 = 254 x 2 + 48

Step 3: We consider the new divisor 254 and the new remainder 48, and apply the division lemma to get

254 = 48 x 5 + 14

We consider the new divisor 48 and the new remainder 14,and apply the division lemma to get

48 = 14 x 3 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 810 and 556 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(48,14) = HCF(254,48) = HCF(556,254) = HCF(810,556) .

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

Step 1: Since 345 > 2, we apply the division lemma to 345 and 2, to get

345 = 2 x 172 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 345 is 1

Notice that 1 = HCF(2,1) = HCF(345,2) .
