HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 343, 12573 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 343, 12573 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 343, 12573 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 343, 12573 is 1.
HCF(343, 12573) = 1
HCF of 343, 12573 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 343, 12573 is 1.
Highest Common Factor of 343,12573 is 1
Step 1: Since 12573 > 343, we apply the division lemma to 12573 and 343, to get
12573 = 343 x 36 + 225
Step 2: Since the reminder 343 ≠ 0, we apply division lemma to 225 and 343, to get
343 = 225 x 1 + 118
Step 3: We consider the new divisor 225 and the new remainder 118, and apply the division lemma to get
225 = 118 x 1 + 107
We consider the new divisor 118 and the new remainder 107,and apply the division lemma to get
118 = 107 x 1 + 11
We consider the new divisor 107 and the new remainder 11,and apply the division lemma to get
107 = 11 x 9 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 343 and 12573 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(107,11) = HCF(118,107) = HCF(225,118) = HCF(343,225) = HCF(12573,343) .
