HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 198, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 917, 198, 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 917, 198, 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 917, 198, 181 is 1.

HCF(917, 198, 181) = 1

Highest common factor (HCF) of 917, 198, 181 is 1.

Highest Common Factor of 917,198,181 using Euclid's algorithm

Highest Common Factor of 917,198,181 is 1

Step 1: Since 917 > 198, we apply the division lemma to 917 and 198, to get

917 = 198 x 4 + 125

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 125 and 198, to get

198 = 125 x 1 + 73

Step 3: We consider the new divisor 125 and the new remainder 73, and apply the division lemma to get

125 = 73 x 1 + 52

We consider the new divisor 73 and the new remainder 52,and apply the division lemma to get

73 = 52 x 1 + 21

We consider the new divisor 52 and the new remainder 21,and apply the division lemma to get

52 = 21 x 2 + 10

We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get

21 = 10 x 2 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 198 is 1

Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(52,21) = HCF(73,52) = HCF(125,73) = HCF(198,125) = HCF(917,198) .

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

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

181 = 1 x 181 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 181 is 1

Notice that 1 = HCF(181,1) .
