HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 633, 489 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 633, 489 is 3 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 633, 489 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 633, 489 is 3.
HCF(633, 489) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 633, 489 is 3.
Step 1: Since 633 > 489, we apply the division lemma to 633 and 489, to get
633 = 489 x 1 + 144
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 144 and 489, to get
489 = 144 x 3 + 57
Step 3: We consider the new divisor 144 and the new remainder 57, and apply the division lemma to get
144 = 57 x 2 + 30
We consider the new divisor 57 and the new remainder 30,and apply the division lemma to get
57 = 30 x 1 + 27
We consider the new divisor 30 and the new remainder 27,and apply the division lemma to get
30 = 27 x 1 + 3
We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 633 and 489 is 3
Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(57,30) = HCF(144,57) = HCF(489,144) = HCF(633,489) .
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 633, 489?
Answer: HCF of 633, 489 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 633, 489 using Euclid's Algorithm?
Answer: For arbitrary numbers 633, 489 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
