HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 286, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 286, 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 286, 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 286, 457 is 1.
HCF(286, 457) = 1
HCF of 286, 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 286, 457 is 1.
Highest Common Factor of 286,457 is 1
Step 1: Since 457 > 286, we apply the division lemma to 457 and 286, to get
457 = 286 x 1 + 171
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 171 and 286, to get
286 = 171 x 1 + 115
Step 3: We consider the new divisor 171 and the new remainder 115, and apply the division lemma to get
171 = 115 x 1 + 56
We consider the new divisor 115 and the new remainder 56,and apply the division lemma to get
115 = 56 x 2 + 3
We consider the new divisor 56 and the new remainder 3,and apply the division lemma to get
56 = 3 x 18 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 286 and 457 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(56,3) = HCF(115,56) = HCF(171,115) = HCF(286,171) = HCF(457,286) .
