HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 2408, 4365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 818, 2408, 4365 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 818, 2408, 4365 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 818, 2408, 4365 is 1.
HCF(818, 2408, 4365) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 818, 2408, 4365 is 1.
Step 1: Since 2408 > 818, we apply the division lemma to 2408 and 818, to get
2408 = 818 x 2 + 772
Step 2: Since the reminder 818 ≠ 0, we apply division lemma to 772 and 818, to get
818 = 772 x 1 + 46
Step 3: We consider the new divisor 772 and the new remainder 46, and apply the division lemma to get
772 = 46 x 16 + 36
We consider the new divisor 46 and the new remainder 36,and apply the division lemma to get
46 = 36 x 1 + 10
We consider the new divisor 36 and the new remainder 10,and apply the division lemma to get
36 = 10 x 3 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 818 and 2408 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(36,10) = HCF(46,36) = HCF(772,46) = HCF(818,772) = HCF(2408,818) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4365 > 2, we apply the division lemma to 4365 and 2, to get
4365 = 2 x 2182 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 4365 is 1
Notice that 1 = HCF(2,1) = HCF(4365,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
