HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 928, 203, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 928, 203, 163 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 928, 203, 163 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 928, 203, 163 is 1.

HCF(928, 203, 163) = 1

Highest common factor (HCF) of 928, 203, 163 is 1.

Highest Common Factor of 928,203,163 using Euclid's algorithm

Highest Common Factor of 928,203,163 is 1

Step 1: Since 928 > 203, we apply the division lemma to 928 and 203, to get

928 = 203 x 4 + 116

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 116 and 203, to get

203 = 116 x 1 + 87

Step 3: We consider the new divisor 116 and the new remainder 87, and apply the division lemma to get

116 = 87 x 1 + 29

We consider the new divisor 87 and the new remainder 29, and apply the division lemma to get

87 = 29 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 928 and 203 is 29

Notice that 29 = HCF(87,29) = HCF(116,87) = HCF(203,116) = HCF(928,203) .

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

Step 1: Since 163 > 29, we apply the division lemma to 163 and 29, to get

163 = 29 x 5 + 18

Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 18 and 29, to get

29 = 18 x 1 + 11

Step 3: We consider the new divisor 18 and the new remainder 11, and apply the division lemma to get

18 = 11 x 1 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 29 and 163 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(29,18) = HCF(163,29) .
