HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 7243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 386, 7243 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 386, 7243 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 386, 7243 is 1.
HCF(386, 7243) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 386, 7243 is 1.
Step 1: Since 7243 > 386, we apply the division lemma to 7243 and 386, to get
7243 = 386 x 18 + 295
Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 295 and 386, to get
386 = 295 x 1 + 91
Step 3: We consider the new divisor 295 and the new remainder 91, and apply the division lemma to get
295 = 91 x 3 + 22
We consider the new divisor 91 and the new remainder 22,and apply the division lemma to get
91 = 22 x 4 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 386 and 7243 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(91,22) = HCF(295,91) = HCF(386,295) = HCF(7243,386) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 386, 7243?
Answer: HCF of 386, 7243 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 386, 7243 using Euclid's Algorithm?
Answer: For arbitrary numbers 386, 7243 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
