HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 118, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 449, 118, 543 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 449, 118, 543 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 449, 118, 543 is 1.
HCF(449, 118, 543) = 1
HCF of 449, 118, 543 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 449, 118, 543 is 1.
Highest Common Factor of 449,118,543 is 1
Step 1: Since 449 > 118, we apply the division lemma to 449 and 118, to get
449 = 118 x 3 + 95
Step 2: Since the reminder 118 ≠ 0, we apply division lemma to 95 and 118, to get
118 = 95 x 1 + 23
Step 3: We consider the new divisor 95 and the new remainder 23, and apply the division lemma to get
95 = 23 x 4 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 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 449 and 118 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(95,23) = HCF(118,95) = HCF(449,118) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 543 > 1, we apply the division lemma to 543 and 1, to get
543 = 1 x 543 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 543 is 1
Notice that 1 = HCF(543,1) .
