HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 473, 549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 278, 473, 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 278, 473, 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 278, 473, 549 is 1.
HCF(278, 473, 549) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 278, 473, 549 is 1.
Step 1: Since 473 > 278, we apply the division lemma to 473 and 278, to get
473 = 278 x 1 + 195
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 195 and 278, to get
278 = 195 x 1 + 83
Step 3: We consider the new divisor 195 and the new remainder 83, and apply the division lemma to get
195 = 83 x 2 + 29
We consider the new divisor 83 and the new remainder 29,and apply the division lemma to get
83 = 29 x 2 + 25
We consider the new divisor 29 and the new remainder 25,and apply the division lemma to get
29 = 25 x 1 + 4
We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get
25 = 4 x 6 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 278 and 473 is 1
Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(83,29) = HCF(195,83) = HCF(278,195) = HCF(473,278) .
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) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 278, 473, 549?
Answer: HCF of 278, 473, 549 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 278, 473, 549 using Euclid's Algorithm?
Answer: For arbitrary numbers 278, 473, 549 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
