HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 215, 828, 556 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 215, 828, 556 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 215, 828, 556 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 215, 828, 556 is 1.

HCF(215, 828, 556) = 1

Highest common factor (HCF) of 215, 828, 556 is 1.

Highest Common Factor of 215,828,556 using Euclid's algorithm

Highest Common Factor of 215,828,556 is 1

Step 1: Since 828 > 215, we apply the division lemma to 828 and 215, to get

828 = 215 x 3 + 183

Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 183 and 215, to get

215 = 183 x 1 + 32

Step 3: We consider the new divisor 183 and the new remainder 32, and apply the division lemma to get

183 = 32 x 5 + 23

We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get

32 = 23 x 1 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 215 and 828 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(183,32) = HCF(215,183) = HCF(828,215) .

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

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

556 = 1 x 556 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 556 is 1

Notice that 1 = HCF(556,1) .
