HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4440, 2649 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 4440, 2649 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 4440, 2649 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 4440, 2649 is 3.
HCF(4440, 2649) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4440, 2649 is 3.
Step 1: Since 4440 > 2649, we apply the division lemma to 4440 and 2649, to get
4440 = 2649 x 1 + 1791
Step 2: Since the reminder 2649 ≠ 0, we apply division lemma to 1791 and 2649, to get
2649 = 1791 x 1 + 858
Step 3: We consider the new divisor 1791 and the new remainder 858, and apply the division lemma to get
1791 = 858 x 2 + 75
We consider the new divisor 858 and the new remainder 75,and apply the division lemma to get
858 = 75 x 11 + 33
We consider the new divisor 75 and the new remainder 33,and apply the division lemma to get
75 = 33 x 2 + 9
We consider the new divisor 33 and the new remainder 9,and apply the division lemma to get
33 = 9 x 3 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 4440 and 2649 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(33,9) = HCF(75,33) = HCF(858,75) = HCF(1791,858) = HCF(2649,1791) = HCF(4440,2649) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
