HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 835, 491, 133, 29 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 835, 491, 133, 29 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 835, 491, 133, 29 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 835, 491, 133, 29 is 1.
HCF(835, 491, 133, 29) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 835, 491, 133, 29 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 835 and 491 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 133 > 1, we apply the division lemma to 133 and 1, to get
133 = 1 x 133 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 133 is 1
Notice that 1 = HCF(133,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 29 > 1, we apply the division lemma to 29 and 1, to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 29 is 1
Notice that 1 = HCF(29,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
