HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 200, 644 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 450, 200, 644 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 450, 200, 644 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 450, 200, 644 is 2.
HCF(450, 200, 644) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 450, 200, 644 is 2.
Step 1: Since 450 > 200, we apply the division lemma to 450 and 200, to get
450 = 200 x 2 + 50
Step 2: Since the reminder 200 ≠ 0, we apply division lemma to 50 and 200, to get
200 = 50 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 50, the HCF of 450 and 200 is 50
Notice that 50 = HCF(200,50) = HCF(450,200) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 644 > 50, we apply the division lemma to 644 and 50, to get
644 = 50 x 12 + 44
Step 2: Since the reminder 50 ≠ 0, we apply division lemma to 44 and 50, to get
50 = 44 x 1 + 6
Step 3: We consider the new divisor 44 and the new remainder 6, and apply the division lemma to get
44 = 6 x 7 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 50 and 644 is 2
Notice that 2 = HCF(6,2) = HCF(44,6) = HCF(50,44) = HCF(644,50) .
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 450, 200, 644?
Answer: HCF of 450, 200, 644 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 450, 200, 644 using Euclid's Algorithm?
Answer: For arbitrary numbers 450, 200, 644 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
