HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 411, 549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 411, 549 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 671, 411, 549 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 671, 411, 549 is 1.
HCF(671, 411, 549) = 1
HCF of 671, 411, 549 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 671, 411, 549 is 1.
Highest Common Factor of 671,411,549 is 1
Step 1: Since 671 > 411, we apply the division lemma to 671 and 411, to get
671 = 411 x 1 + 260
Step 2: Since the reminder 411 ≠ 0, we apply division lemma to 260 and 411, to get
411 = 260 x 1 + 151
Step 3: We consider the new divisor 260 and the new remainder 151, and apply the division lemma to get
260 = 151 x 1 + 109
We consider the new divisor 151 and the new remainder 109,and apply the division lemma to get
151 = 109 x 1 + 42
We consider the new divisor 109 and the new remainder 42,and apply the division lemma to get
109 = 42 x 2 + 25
We consider the new divisor 42 and the new remainder 25,and apply the division lemma to get
42 = 25 x 1 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 411 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(42,25) = HCF(109,42) = HCF(151,109) = HCF(260,151) = HCF(411,260) = HCF(671,411) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 549 > 1, we apply the division lemma to 549 and 1, to get
549 = 1 x 549 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 549 is 1
Notice that 1 = HCF(549,1) .
