HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 249, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 249, 326 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 249, 326 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 249, 326 is 1.
HCF(249, 326) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 249, 326 is 1.
Step 1: Since 326 > 249, we apply the division lemma to 326 and 249, to get
326 = 249 x 1 + 77
Step 2: Since the reminder 249 ≠ 0, we apply division lemma to 77 and 249, to get
249 = 77 x 3 + 18
Step 3: We consider the new divisor 77 and the new remainder 18, and apply the division lemma to get
77 = 18 x 4 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 249 and 326 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(77,18) = HCF(249,77) = HCF(326,249) .
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 249, 326?
Answer: HCF of 249, 326 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 249, 326 using Euclid's Algorithm?
Answer: For arbitrary numbers 249, 326 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
