HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 813 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 813 is 3 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 240, 813 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 240, 813 is 3.
HCF(240, 813) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 813 is 3.
Step 1: Since 813 > 240, we apply the division lemma to 813 and 240, to get
813 = 240 x 3 + 93
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 93 and 240, to get
240 = 93 x 2 + 54
Step 3: We consider the new divisor 93 and the new remainder 54, and apply the division lemma to get
93 = 54 x 1 + 39
We consider the new divisor 54 and the new remainder 39,and apply the division lemma to get
54 = 39 x 1 + 15
We consider the new divisor 39 and the new remainder 15,and apply the division lemma to get
39 = 15 x 2 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 240 and 813 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(39,15) = HCF(54,39) = HCF(93,54) = HCF(240,93) = HCF(813,240) .
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 240, 813?
Answer: HCF of 240, 813 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 240, 813 using Euclid's Algorithm?
Answer: For arbitrary numbers 240, 813 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
