HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 801, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 285, 801, 145 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 285, 801, 145 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 285, 801, 145 is 1.
HCF(285, 801, 145) = 1
HCF of 285, 801, 145 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 285, 801, 145 is 1.
Highest Common Factor of 285,801,145 is 1
Step 1: Since 801 > 285, we apply the division lemma to 801 and 285, to get
801 = 285 x 2 + 231
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 231 and 285, to get
285 = 231 x 1 + 54
Step 3: We consider the new divisor 231 and the new remainder 54, and apply the division lemma to get
231 = 54 x 4 + 15
We consider the new divisor 54 and the new remainder 15,and apply the division lemma to get
54 = 15 x 3 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 285 and 801 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(231,54) = HCF(285,231) = HCF(801,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 3, we apply the division lemma to 145 and 3, to get
145 = 3 x 48 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 145 is 1
Notice that 1 = HCF(3,1) = HCF(145,3) .
