HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 195, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 195, 433 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 905, 195, 433 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 905, 195, 433 is 1.
HCF(905, 195, 433) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 905, 195, 433 is 1.
Step 1: Since 905 > 195, we apply the division lemma to 905 and 195, to get
905 = 195 x 4 + 125
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 125 and 195, to get
195 = 125 x 1 + 70
Step 3: We consider the new divisor 125 and the new remainder 70, and apply the division lemma to get
125 = 70 x 1 + 55
We consider the new divisor 70 and the new remainder 55,and apply the division lemma to get
70 = 55 x 1 + 15
We consider the new divisor 55 and the new remainder 15,and apply the division lemma to get
55 = 15 x 3 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 905 and 195 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(55,15) = HCF(70,55) = HCF(125,70) = HCF(195,125) = HCF(905,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 433 > 5, we apply the division lemma to 433 and 5, to get
433 = 5 x 86 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 433 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(433,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
