HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 867, 365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 867, 365 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 393, 867, 365 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 393, 867, 365 is 1.
HCF(393, 867, 365) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 393, 867, 365 is 1.
Step 1: Since 867 > 393, we apply the division lemma to 867 and 393, to get
867 = 393 x 2 + 81
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 81 and 393, to get
393 = 81 x 4 + 69
Step 3: We consider the new divisor 81 and the new remainder 69, and apply the division lemma to get
81 = 69 x 1 + 12
We consider the new divisor 69 and the new remainder 12,and apply the division lemma to get
69 = 12 x 5 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 393 and 867 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(69,12) = HCF(81,69) = HCF(393,81) = HCF(867,393) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 365 > 3, we apply the division lemma to 365 and 3, to get
365 = 3 x 121 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 365 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(365,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 393, 867, 365?
Answer: HCF of 393, 867, 365 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 393, 867, 365 using Euclid's Algorithm?
Answer: For arbitrary numbers 393, 867, 365 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
