HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 143, 343 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 143, 343 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 143, 343 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 143, 343 is 1.
HCF(143, 343) = 1
HCF of 143, 343 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 143, 343 is 1.
Highest Common Factor of 143,343 is 1
Step 1: Since 343 > 143, we apply the division lemma to 343 and 143, to get
343 = 143 x 2 + 57
Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 57 and 143, to get
143 = 57 x 2 + 29
Step 3: We consider the new divisor 57 and the new remainder 29, and apply the division lemma to get
57 = 29 x 1 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 143 and 343 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(57,29) = HCF(143,57) = HCF(343,143) .
