HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 808, 201 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 501, 808, 201 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 501, 808, 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 501, 808, 201 is 1.
HCF(501, 808, 201) = 1
HCF of 501, 808, 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 501, 808, 201 is 1.
Highest Common Factor of 501,808,201 is 1
Step 1: Since 808 > 501, we apply the division lemma to 808 and 501, to get
808 = 501 x 1 + 307
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 307 and 501, to get
501 = 307 x 1 + 194
Step 3: We consider the new divisor 307 and the new remainder 194, and apply the division lemma to get
307 = 194 x 1 + 113
We consider the new divisor 194 and the new remainder 113,and apply the division lemma to get
194 = 113 x 1 + 81
We consider the new divisor 113 and the new remainder 81,and apply the division lemma to get
113 = 81 x 1 + 32
We consider the new divisor 81 and the new remainder 32,and apply the division lemma to get
81 = 32 x 2 + 17
We consider the new divisor 32 and the new remainder 17,and apply the division lemma to get
32 = 17 x 1 + 15
We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get
17 = 15 x 1 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 501 and 808 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(32,17) = HCF(81,32) = HCF(113,81) = HCF(194,113) = HCF(307,194) = HCF(501,307) = HCF(808,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 201 > 1, we apply the division lemma to 201 and 1, to get
201 = 1 x 201 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 201 is 1
Notice that 1 = HCF(201,1) .
