HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 800, 200, 784 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 800, 200, 784 is 8 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 800, 200, 784 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 800, 200, 784 is 8.
HCF(800, 200, 784) = 8
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 800, 200, 784 is 8.
Step 1: Since 800 > 200, we apply the division lemma to 800 and 200, to get
800 = 200 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 200, the HCF of 800 and 200 is 200
Notice that 200 = HCF(800,200) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 784 > 200, we apply the division lemma to 784 and 200, to get
784 = 200 x 3 + 184
Step 2: Since the reminder 200 ≠ 0, we apply division lemma to 184 and 200, to get
200 = 184 x 1 + 16
Step 3: We consider the new divisor 184 and the new remainder 16, and apply the division lemma to get
184 = 16 x 11 + 8
We consider the new divisor 16 and the new remainder 8, and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 200 and 784 is 8
Notice that 8 = HCF(16,8) = HCF(184,16) = HCF(200,184) = HCF(784,200) .
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 800, 200, 784?
Answer: HCF of 800, 200, 784 is 8 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 800, 200, 784 using Euclid's Algorithm?
Answer: For arbitrary numbers 800, 200, 784 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
