HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2436, 7791 i.e. 21 the largest integer that leaves a remainder zero for all numbers.
HCF of 2436, 7791 is 21 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 2436, 7791 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 2436, 7791 is 21.
HCF(2436, 7791) = 21
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2436, 7791 is 21.
Step 1: Since 7791 > 2436, we apply the division lemma to 7791 and 2436, to get
7791 = 2436 x 3 + 483
Step 2: Since the reminder 2436 ≠ 0, we apply division lemma to 483 and 2436, to get
2436 = 483 x 5 + 21
Step 3: We consider the new divisor 483 and the new remainder 21, and apply the division lemma to get
483 = 21 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 2436 and 7791 is 21
Notice that 21 = HCF(483,21) = HCF(2436,483) = HCF(7791,2436) .
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 2436, 7791?
Answer: HCF of 2436, 7791 is 21 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 2436, 7791 using Euclid's Algorithm?
Answer: For arbitrary numbers 2436, 7791 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
