HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 241, 255, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 361, 241, 255, 243 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 361, 241, 255, 243 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 361, 241, 255, 243 is 1.
HCF(361, 241, 255, 243) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 361, 241, 255, 243 is 1.
Step 1: Since 361 > 241, we apply the division lemma to 361 and 241, to get
361 = 241 x 1 + 120
Step 2: Since the reminder 241 ≠ 0, we apply division lemma to 120 and 241, to get
241 = 120 x 2 + 1
Step 3: We consider the new divisor 120 and the new remainder 1, and apply the division lemma to get
120 = 1 x 120 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 361 and 241 is 1
Notice that 1 = HCF(120,1) = HCF(241,120) = HCF(361,241) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get
255 = 1 x 255 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1
Notice that 1 = HCF(255,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 243 > 1, we apply the division lemma to 243 and 1, to get
243 = 1 x 243 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 243 is 1
Notice that 1 = HCF(243,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 361, 241, 255, 243?
Answer: HCF of 361, 241, 255, 243 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 361, 241, 255, 243 using Euclid's Algorithm?
Answer: For arbitrary numbers 361, 241, 255, 243 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
