HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 521, 313 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 521, 313 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 521, 313 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 521, 313 is 1.
HCF(521, 313) = 1
HCF of 521, 313 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 521, 313 is 1.
Highest Common Factor of 521,313 is 1
Step 1: Since 521 > 313, we apply the division lemma to 521 and 313, to get
521 = 313 x 1 + 208
Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 208 and 313, to get
313 = 208 x 1 + 105
Step 3: We consider the new divisor 208 and the new remainder 105, and apply the division lemma to get
208 = 105 x 1 + 103
We consider the new divisor 105 and the new remainder 103,and apply the division lemma to get
105 = 103 x 1 + 2
We consider the new divisor 103 and the new remainder 2,and apply the division lemma to get
103 = 2 x 51 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 521 and 313 is 1
Notice that 1 = HCF(2,1) = HCF(103,2) = HCF(105,103) = HCF(208,105) = HCF(313,208) = HCF(521,313) .
