HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 294 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 543, 294 is 3 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 543, 294 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 543, 294 is 3.
HCF(543, 294) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 543, 294 is 3.
Step 1: Since 543 > 294, we apply the division lemma to 543 and 294, to get
543 = 294 x 1 + 249
Step 2: Since the reminder 294 ≠ 0, we apply division lemma to 249 and 294, to get
294 = 249 x 1 + 45
Step 3: We consider the new divisor 249 and the new remainder 45, and apply the division lemma to get
249 = 45 x 5 + 24
We consider the new divisor 45 and the new remainder 24,and apply the division lemma to get
45 = 24 x 1 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 543 and 294 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(45,24) = HCF(249,45) = HCF(294,249) = HCF(543,294) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 543, 294?
Answer: HCF of 543, 294 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 543, 294 using Euclid's Algorithm?
Answer: For arbitrary numbers 543, 294 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
