HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 112, 553, 250, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 112, 553, 250, 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 112, 553, 250, 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 112, 553, 250, 243 is 1.
HCF(112, 553, 250, 243) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 112, 553, 250, 243 is 1.
Step 1: Since 553 > 112, we apply the division lemma to 553 and 112, to get
553 = 112 x 4 + 105
Step 2: Since the reminder 112 ≠ 0, we apply division lemma to 105 and 112, to get
112 = 105 x 1 + 7
Step 3: We consider the new divisor 105 and the new remainder 7, and apply the division lemma to get
105 = 7 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 112 and 553 is 7
Notice that 7 = HCF(105,7) = HCF(112,105) = HCF(553,112) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 250 > 7, we apply the division lemma to 250 and 7, to get
250 = 7 x 35 + 5
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 5 and 7, to get
7 = 5 x 1 + 2
Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 250 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(250,7) .
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 112, 553, 250, 243?
Answer: HCF of 112, 553, 250, 243 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 112, 553, 250, 243 using Euclid's Algorithm?
Answer: For arbitrary numbers 112, 553, 250, 243 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
