HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 1451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 1451 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 404, 1451 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 404, 1451 is 1.
HCF(404, 1451) = 1
HCF of 404, 1451 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 404, 1451 is 1.
Highest Common Factor of 404,1451 is 1
Step 1: Since 1451 > 404, we apply the division lemma to 1451 and 404, to get
1451 = 404 x 3 + 239
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 239 and 404, to get
404 = 239 x 1 + 165
Step 3: We consider the new divisor 239 and the new remainder 165, and apply the division lemma to get
239 = 165 x 1 + 74
We consider the new divisor 165 and the new remainder 74,and apply the division lemma to get
165 = 74 x 2 + 17
We consider the new divisor 74 and the new remainder 17,and apply the division lemma to get
74 = 17 x 4 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 404 and 1451 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(74,17) = HCF(165,74) = HCF(239,165) = HCF(404,239) = HCF(1451,404) .
