HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 903, 349, 26 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 903, 349, 26 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 903, 349, 26 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 903, 349, 26 is 1.

HCF(903, 349, 26) = 1

Highest common factor (HCF) of 903, 349, 26 is 1.

Highest Common Factor of 903,349,26 using Euclid's algorithm

Highest Common Factor of 903,349,26 is 1

Step 1: Since 903 > 349, we apply the division lemma to 903 and 349, to get

903 = 349 x 2 + 205

Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 205 and 349, to get

349 = 205 x 1 + 144

Step 3: We consider the new divisor 205 and the new remainder 144, and apply the division lemma to get

205 = 144 x 1 + 61

We consider the new divisor 144 and the new remainder 61,and apply the division lemma to get

144 = 61 x 2 + 22

We consider the new divisor 61 and the new remainder 22,and apply the division lemma to get

61 = 22 x 2 + 17

We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get

22 = 17 x 1 + 5

We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get

17 = 5 x 3 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 903 and 349 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(61,22) = HCF(144,61) = HCF(205,144) = HCF(349,205) = HCF(903,349) .


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

Step 1: Since 26 > 1, we apply the division lemma to 26 and 1, to get

26 = 1 x 26 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 26 is 1

Notice that 1 = HCF(26,1) .
