HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 838, 403, 828 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 838, 403, 828 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 497, 838, 403, 828 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 497, 838, 403, 828 is 1.
HCF(497, 838, 403, 828) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 838, 403, 828 is 1.
Step 1: Since 838 > 497, we apply the division lemma to 838 and 497, to get
838 = 497 x 1 + 341
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 341 and 497, to get
497 = 341 x 1 + 156
Step 3: We consider the new divisor 341 and the new remainder 156, and apply the division lemma to get
341 = 156 x 2 + 29
We consider the new divisor 156 and the new remainder 29,and apply the division lemma to get
156 = 29 x 5 + 11
We consider the new divisor 29 and the new remainder 11,and apply the division lemma to get
29 = 11 x 2 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 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 497 and 838 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(156,29) = HCF(341,156) = HCF(497,341) = HCF(838,497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 403 > 1, we apply the division lemma to 403 and 1, to get
403 = 1 x 403 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 403 is 1
Notice that 1 = HCF(403,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 828 > 1, we apply the division lemma to 828 and 1, to get
828 = 1 x 828 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 828 is 1
Notice that 1 = HCF(828,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
