HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 7243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 7243 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 315, 7243 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 315, 7243 is 1.
HCF(315, 7243) = 1
HCF of 315, 7243 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 7243 is 1.
Highest Common Factor of 315,7243 is 1
Step 1: Since 7243 > 315, we apply the division lemma to 7243 and 315, to get
7243 = 315 x 22 + 313
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 313 and 315, to get
315 = 313 x 1 + 2
Step 3: We consider the new divisor 313 and the new remainder 2, and apply the division lemma to get
313 = 2 x 156 + 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 315 and 7243 is 1
Notice that 1 = HCF(2,1) = HCF(313,2) = HCF(315,313) = HCF(7243,315) .
