HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 660, 201 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 660, 201 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 240, 660, 201 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 240, 660, 201 is 3.
HCF(240, 660, 201) = 3
HCF of 240, 660, 201 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 660, 201 is 3.
Highest Common Factor of 240,660,201 is 3
Step 1: Since 660 > 240, we apply the division lemma to 660 and 240, to get
660 = 240 x 2 + 180
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 180 and 240, to get
240 = 180 x 1 + 60
Step 3: We consider the new divisor 180 and the new remainder 60, and apply the division lemma to get
180 = 60 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 60, the HCF of 240 and 660 is 60
Notice that 60 = HCF(180,60) = HCF(240,180) = HCF(660,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 201 > 60, we apply the division lemma to 201 and 60, to get
201 = 60 x 3 + 21
Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 21 and 60, to get
60 = 21 x 2 + 18
Step 3: We consider the new divisor 21 and the new remainder 18, and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3, and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 60 and 201 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(201,60) .
