HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 7451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 7451 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 515, 7451 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 515, 7451 is 1.
HCF(515, 7451) = 1
HCF of 515, 7451 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 7451 is 1.
Highest Common Factor of 515,7451 is 1
Step 1: Since 7451 > 515, we apply the division lemma to 7451 and 515, to get
7451 = 515 x 14 + 241
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 241 and 515, to get
515 = 241 x 2 + 33
Step 3: We consider the new divisor 241 and the new remainder 33, and apply the division lemma to get
241 = 33 x 7 + 10
We consider the new divisor 33 and the new remainder 10,and apply the division lemma to get
33 = 10 x 3 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 515 and 7451 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(33,10) = HCF(241,33) = HCF(515,241) = HCF(7451,515) .
