HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 549, 209 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 549, 209 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 549, 209 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 549, 209 is 1.
HCF(549, 209) = 1
HCF of 549, 209 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 549, 209 is 1.
Highest Common Factor of 549,209 is 1
Step 1: Since 549 > 209, we apply the division lemma to 549 and 209, to get
549 = 209 x 2 + 131
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 131 and 209, to get
209 = 131 x 1 + 78
Step 3: We consider the new divisor 131 and the new remainder 78, and apply the division lemma to get
131 = 78 x 1 + 53
We consider the new divisor 78 and the new remainder 53,and apply the division lemma to get
78 = 53 x 1 + 25
We consider the new divisor 53 and the new remainder 25,and apply the division lemma to get
53 = 25 x 2 + 3
We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get
25 = 3 x 8 + 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 549 and 209 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(53,25) = HCF(78,53) = HCF(131,78) = HCF(209,131) = HCF(549,209) .
