HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 313, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 313, 661 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 313, 661 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 313, 661 is 1.
HCF(313, 661) = 1
HCF of 313, 661 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 313, 661 is 1.
Highest Common Factor of 313,661 is 1
Step 1: Since 661 > 313, we apply the division lemma to 661 and 313, to get
661 = 313 x 2 + 35
Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 35 and 313, to get
313 = 35 x 8 + 33
Step 3: We consider the new divisor 35 and the new remainder 33, and apply the division lemma to get
35 = 33 x 1 + 2
We consider the new divisor 33 and the new remainder 2,and apply the division lemma to get
33 = 2 x 16 + 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 313 and 661 is 1
Notice that 1 = HCF(2,1) = HCF(33,2) = HCF(35,33) = HCF(313,35) = HCF(661,313) .
