HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 693, 486 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 447, 693, 486 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 447, 693, 486 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, 693, 486 is 3.
HCF(447, 693, 486) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 447, 693, 486 is 3.
Step 1: Since 693 > 447, we apply the division lemma to 693 and 447, to get
693 = 447 x 1 + 246
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 246 and 447, to get
447 = 246 x 1 + 201
Step 3: We consider the new divisor 246 and the new remainder 201, and apply the division lemma to get
246 = 201 x 1 + 45
We consider the new divisor 201 and the new remainder 45,and apply the division lemma to get
201 = 45 x 4 + 21
We consider the new divisor 45 and the new remainder 21,and apply the division lemma to get
45 = 21 x 2 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 447 and 693 is 3
Notice that 3 = HCF(21,3) = HCF(45,21) = HCF(201,45) = HCF(246,201) = HCF(447,246) = HCF(693,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 486 > 3, we apply the division lemma to 486 and 3, to get
486 = 3 x 162 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 486 is 3
Notice that 3 = HCF(486,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
