HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 901, 316, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 901, 316, 189 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 901, 316, 189 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 901, 316, 189 is 1.

HCF(901, 316, 189) = 1

Highest common factor (HCF) of 901, 316, 189 is 1.

Highest Common Factor of 901,316,189 using Euclid's algorithm

Highest Common Factor of 901,316,189 is 1

Step 1: Since 901 > 316, we apply the division lemma to 901 and 316, to get

901 = 316 x 2 + 269

Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 269 and 316, to get

316 = 269 x 1 + 47

Step 3: We consider the new divisor 269 and the new remainder 47, and apply the division lemma to get

269 = 47 x 5 + 34

We consider the new divisor 47 and the new remainder 34,and apply the division lemma to get

47 = 34 x 1 + 13

We consider the new divisor 34 and the new remainder 13,and apply the division lemma to get

34 = 13 x 2 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 901 and 316 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(47,34) = HCF(269,47) = HCF(316,269) = HCF(901,316) .

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

Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get

189 = 1 x 189 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1

Notice that 1 = HCF(189,1) .
