HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 501, 813 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 408, 501, 813 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 408, 501, 813 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 408, 501, 813 is 3.
HCF(408, 501, 813) = 3
HCF of 408, 501, 813 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 408, 501, 813 is 3.
Highest Common Factor of 408,501,813 is 3
Step 1: Since 501 > 408, we apply the division lemma to 501 and 408, to get
501 = 408 x 1 + 93
Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 93 and 408, to get
408 = 93 x 4 + 36
Step 3: We consider the new divisor 93 and the new remainder 36, and apply the division lemma to get
93 = 36 x 2 + 21
We consider the new divisor 36 and the new remainder 21,and apply the division lemma to get
36 = 21 x 1 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 408 and 501 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(36,21) = HCF(93,36) = HCF(408,93) = HCF(501,408) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 813 > 3, we apply the division lemma to 813 and 3, to get
813 = 3 x 271 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 813 is 3
Notice that 3 = HCF(813,3) .
