HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 2155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 447, 2155 is 1 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 447, 2155 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 447, 2155 is 1.
HCF(447, 2155) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 447, 2155 is 1.
Step 1: Since 2155 > 447, we apply the division lemma to 2155 and 447, to get
2155 = 447 x 4 + 367
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 367 and 447, to get
447 = 367 x 1 + 80
Step 3: We consider the new divisor 367 and the new remainder 80, and apply the division lemma to get
367 = 80 x 4 + 47
We consider the new divisor 80 and the new remainder 47,and apply the division lemma to get
80 = 47 x 1 + 33
We consider the new divisor 47 and the new remainder 33,and apply the division lemma to get
47 = 33 x 1 + 14
We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get
33 = 14 x 2 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 447 and 2155 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(47,33) = HCF(80,47) = HCF(367,80) = HCF(447,367) = HCF(2155,447) .
Here are some samples of HCF using Euclid's Algorithm calculations.
