HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 287, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 468, 287, 12 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 468, 287, 12 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 468, 287, 12 is 1.
HCF(468, 287, 12) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 468, 287, 12 is 1.
Step 1: Since 468 > 287, we apply the division lemma to 468 and 287, to get
468 = 287 x 1 + 181
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 181 and 287, to get
287 = 181 x 1 + 106
Step 3: We consider the new divisor 181 and the new remainder 106, and apply the division lemma to get
181 = 106 x 1 + 75
We consider the new divisor 106 and the new remainder 75,and apply the division lemma to get
106 = 75 x 1 + 31
We consider the new divisor 75 and the new remainder 31,and apply the division lemma to get
75 = 31 x 2 + 13
We consider the new divisor 31 and the new remainder 13,and apply the division lemma to get
31 = 13 x 2 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
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 468 and 287 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(31,13) = HCF(75,31) = HCF(106,75) = HCF(181,106) = HCF(287,181) = HCF(468,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
