HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 812 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 812 is 2 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 242, 812 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 242, 812 is 2.
HCF(242, 812) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 242, 812 is 2.
Step 1: Since 812 > 242, we apply the division lemma to 812 and 242, to get
812 = 242 x 3 + 86
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 86 and 242, to get
242 = 86 x 2 + 70
Step 3: We consider the new divisor 86 and the new remainder 70, and apply the division lemma to get
86 = 70 x 1 + 16
We consider the new divisor 70 and the new remainder 16,and apply the division lemma to get
70 = 16 x 4 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 242 and 812 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(70,16) = HCF(86,70) = HCF(242,86) = HCF(812,242) .
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 242, 812?
Answer: HCF of 242, 812 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 242, 812 using Euclid's Algorithm?
Answer: For arbitrary numbers 242, 812 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
