HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 844, 326, 449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 844, 326, 449 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 844, 326, 449 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 844, 326, 449 is 1.
HCF(844, 326, 449) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 844, 326, 449 is 1.
Step 1: Since 844 > 326, we apply the division lemma to 844 and 326, to get
844 = 326 x 2 + 192
Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 192 and 326, to get
326 = 192 x 1 + 134
Step 3: We consider the new divisor 192 and the new remainder 134, and apply the division lemma to get
192 = 134 x 1 + 58
We consider the new divisor 134 and the new remainder 58,and apply the division lemma to get
134 = 58 x 2 + 18
We consider the new divisor 58 and the new remainder 18,and apply the division lemma to get
58 = 18 x 3 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 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 844 and 326 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(58,18) = HCF(134,58) = HCF(192,134) = HCF(326,192) = HCF(844,326) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 449 > 2, we apply the division lemma to 449 and 2, to get
449 = 2 x 224 + 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 449 is 1
Notice that 1 = HCF(2,1) = HCF(449,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
