HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 275, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 550, 275, 743 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 550, 275, 743 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 550, 275, 743 is 1.
HCF(550, 275, 743) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 550, 275, 743 is 1.
Step 1: Since 550 > 275, we apply the division lemma to 550 and 275, to get
550 = 275 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 275, the HCF of 550 and 275 is 275
Notice that 275 = HCF(550,275) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 743 > 275, we apply the division lemma to 743 and 275, to get
743 = 275 x 2 + 193
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 193 and 275, to get
275 = 193 x 1 + 82
Step 3: We consider the new divisor 193 and the new remainder 82, and apply the division lemma to get
193 = 82 x 2 + 29
We consider the new divisor 82 and the new remainder 29,and apply the division lemma to get
82 = 29 x 2 + 24
We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get
29 = 24 x 1 + 5
We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get
24 = 5 x 4 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 275 and 743 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(82,29) = HCF(193,82) = HCF(275,193) = HCF(743,275) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 550, 275, 743?
Answer: HCF of 550, 275, 743 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 550, 275, 743 using Euclid's Algorithm?
Answer: For arbitrary numbers 550, 275, 743 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
