HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 228, 7021, 3155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 228, 7021, 3155 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 228, 7021, 3155 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 228, 7021, 3155 is 1.

HCF(228, 7021, 3155) = 1

HCF of 228, 7021, 3155 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 228, 7021, 3155 is 1.

Highest Common Factor of 228,7021,3155 using Euclid's algorithm

Highest Common Factor of 228,7021,3155 is 1

Step 1: Since 7021 > 228, we apply the division lemma to 7021 and 228, to get

7021 = 228 x 30 + 181

Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 181 and 228, to get

228 = 181 x 1 + 47

Step 3: We consider the new divisor 181 and the new remainder 47, and apply the division lemma to get

181 = 47 x 3 + 40

We consider the new divisor 47 and the new remainder 40,and apply the division lemma to get

47 = 40 x 1 + 7

We consider the new divisor 40 and the new remainder 7,and apply the division lemma to get

40 = 7 x 5 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 228 and 7021 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(40,7) = HCF(47,40) = HCF(181,47) = HCF(228,181) = HCF(7021,228) .


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

Step 1: Since 3155 > 1, we apply the division lemma to 3155 and 1, to get

3155 = 1 x 3155 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3155 is 1

Notice that 1 = HCF(3155,1) .
