HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 463, 403 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 463, 403 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 68, 463, 403 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 68, 463, 403 is 1.
HCF(68, 463, 403) = 1
HCF of 68, 463, 403 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 463, 403 is 1.
Highest Common Factor of 68,463,403 is 1
Step 1: Since 463 > 68, we apply the division lemma to 463 and 68, to get
463 = 68 x 6 + 55
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 55 and 68, to get
68 = 55 x 1 + 13
Step 3: We consider the new divisor 55 and the new remainder 13, and apply the division lemma to get
55 = 13 x 4 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 68 and 463 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(55,13) = HCF(68,55) = HCF(463,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 403 > 1, we apply the division lemma to 403 and 1, to get
403 = 1 x 403 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 403 is 1
Notice that 1 = HCF(403,1) .
