HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 407, 401 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 503, 407, 401 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 503, 407, 401 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 503, 407, 401 is 1.
HCF(503, 407, 401) = 1
HCF of 503, 407, 401 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 503, 407, 401 is 1.
Highest Common Factor of 503,407,401 is 1
Step 1: Since 503 > 407, we apply the division lemma to 503 and 407, to get
503 = 407 x 1 + 96
Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 96 and 407, to get
407 = 96 x 4 + 23
Step 3: We consider the new divisor 96 and the new remainder 23, and apply the division lemma to get
96 = 23 x 4 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 503 and 407 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(96,23) = HCF(407,96) = HCF(503,407) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 401 > 1, we apply the division lemma to 401 and 1, to get
401 = 1 x 401 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 401 is 1
Notice that 1 = HCF(401,1) .
