HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 1443 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 1443 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 486, 1443 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 486, 1443 is 3.
HCF(486, 1443) = 3
HCF of 486, 1443 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 1443 is 3.
Highest Common Factor of 486,1443 is 3
Step 1: Since 1443 > 486, we apply the division lemma to 1443 and 486, to get
1443 = 486 x 2 + 471
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 471 and 486, to get
486 = 471 x 1 + 15
Step 3: We consider the new divisor 471 and the new remainder 15, and apply the division lemma to get
471 = 15 x 31 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 486 and 1443 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(471,15) = HCF(486,471) = HCF(1443,486) .
