HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 445, 811, 899 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 445, 811, 899 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 445, 811, 899 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 445, 811, 899 is 1.
HCF(445, 811, 899) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 445, 811, 899 is 1.
Step 1: Since 811 > 445, we apply the division lemma to 811 and 445, to get
811 = 445 x 1 + 366
Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 366 and 445, to get
445 = 366 x 1 + 79
Step 3: We consider the new divisor 366 and the new remainder 79, and apply the division lemma to get
366 = 79 x 4 + 50
We consider the new divisor 79 and the new remainder 50,and apply the division lemma to get
79 = 50 x 1 + 29
We consider the new divisor 50 and the new remainder 29,and apply the division lemma to get
50 = 29 x 1 + 21
We consider the new divisor 29 and the new remainder 21,and apply the division lemma to get
29 = 21 x 1 + 8
We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get
21 = 8 x 2 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 445 and 811 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(29,21) = HCF(50,29) = HCF(79,50) = HCF(366,79) = HCF(445,366) = HCF(811,445) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 899 > 1, we apply the division lemma to 899 and 1, to get
899 = 1 x 899 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 899 is 1
Notice that 1 = HCF(899,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
