HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 901, 349, 459 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 901, 349, 459 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, 349, 459 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, 349, 459 is 1.

HCF(901, 349, 459) = 1

Highest common factor (HCF) of 901, 349, 459 is 1.

Highest Common Factor of 901,349,459 using Euclid's algorithm

Highest Common Factor of 901,349,459 is 1

Step 1: Since 901 > 349, we apply the division lemma to 901 and 349, to get

901 = 349 x 2 + 203

Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 203 and 349, to get

349 = 203 x 1 + 146

Step 3: We consider the new divisor 203 and the new remainder 146, and apply the division lemma to get

203 = 146 x 1 + 57

We consider the new divisor 146 and the new remainder 57,and apply the division lemma to get

146 = 57 x 2 + 32

We consider the new divisor 57 and the new remainder 32,and apply the division lemma to get

57 = 32 x 1 + 25

We consider the new divisor 32 and the new remainder 25,and apply the division lemma to get

32 = 25 x 1 + 7

We consider the new divisor 25 and the new remainder 7,and apply the division lemma to get

25 = 7 x 3 + 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 901 and 349 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(32,25) = HCF(57,32) = HCF(146,57) = HCF(203,146) = HCF(349,203) = HCF(901,349) .

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

Step 1: Since 459 > 1, we apply the division lemma to 459 and 1, to get

459 = 1 x 459 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 459 is 1

Notice that 1 = HCF(459,1) .
