HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 443, 242, 585 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 443, 242, 585 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 443, 242, 585 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 443, 242, 585 is 1.
HCF(443, 242, 585) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 443, 242, 585 is 1.
Step 1: Since 443 > 242, we apply the division lemma to 443 and 242, to get
443 = 242 x 1 + 201
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 201 and 242, to get
242 = 201 x 1 + 41
Step 3: We consider the new divisor 201 and the new remainder 41, and apply the division lemma to get
201 = 41 x 4 + 37
We consider the new divisor 41 and the new remainder 37,and apply the division lemma to get
41 = 37 x 1 + 4
We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get
37 = 4 x 9 + 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 443 and 242 is 1
Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(41,37) = HCF(201,41) = HCF(242,201) = HCF(443,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 585 > 1, we apply the division lemma to 585 and 1, to get
585 = 1 x 585 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 585 is 1
Notice that 1 = HCF(585,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
