HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 528, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 998, 528, 181 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 998, 528, 181 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 998, 528, 181 is 1.

HCF(998, 528, 181) = 1

Highest common factor (HCF) of 998, 528, 181 is 1.

Highest Common Factor of 998,528,181 using Euclid's algorithm

Highest Common Factor of 998,528,181 is 1

Step 1: Since 998 > 528, we apply the division lemma to 998 and 528, to get

998 = 528 x 1 + 470

Step 2: Since the reminder 528 ≠ 0, we apply division lemma to 470 and 528, to get

528 = 470 x 1 + 58

Step 3: We consider the new divisor 470 and the new remainder 58, and apply the division lemma to get

470 = 58 x 8 + 6

We consider the new divisor 58 and the new remainder 6,and apply the division lemma to get

58 = 6 x 9 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 998 and 528 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(58,6) = HCF(470,58) = HCF(528,470) = HCF(998,528) .

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

Step 1: Since 181 > 2, we apply the division lemma to 181 and 2, to get

181 = 2 x 90 + 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 181 is 1

Notice that 1 = HCF(2,1) = HCF(181,2) .
