HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 835, 135 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 491, 835, 135 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 491, 835, 135 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 491, 835, 135 is 1.

HCF(491, 835, 135) = 1

Highest common factor (HCF) of 491, 835, 135 is 1.

Highest Common Factor of 491,835,135 using Euclid's algorithm

Highest Common Factor of 491,835,135 is 1

Step 1: Since 835 > 491, we apply the division lemma to 835 and 491, to get

835 = 491 x 1 + 344

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 344 and 491, to get

491 = 344 x 1 + 147

Step 3: We consider the new divisor 344 and the new remainder 147, and apply the division lemma to get

344 = 147 x 2 + 50

We consider the new divisor 147 and the new remainder 50,and apply the division lemma to get

147 = 50 x 2 + 47

We consider the new divisor 50 and the new remainder 47,and apply the division lemma to get

50 = 47 x 1 + 3

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

47 = 3 x 15 + 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 491 and 835 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(50,47) = HCF(147,50) = HCF(344,147) = HCF(491,344) = HCF(835,491) .


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

Step 1: Since 135 > 1, we apply the division lemma to 135 and 1, to get

135 = 1 x 135 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 135 is 1

Notice that 1 = HCF(135,1) .
