HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 115, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 115, 457 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 115, 457 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 115, 457 is 1.
HCF(115, 457) = 1
HCF of 115, 457 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 115, 457 is 1.
Highest Common Factor of 115,457 is 1
Step 1: Since 457 > 115, we apply the division lemma to 457 and 115, to get
457 = 115 x 3 + 112
Step 2: Since the reminder 115 ≠ 0, we apply division lemma to 112 and 115, to get
115 = 112 x 1 + 3
Step 3: We consider the new divisor 112 and the new remainder 3, and apply the division lemma to get
112 = 3 x 37 + 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 115 and 457 is 1
Notice that 1 = HCF(3,1) = HCF(112,3) = HCF(115,112) = HCF(457,115) .
