HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 629, 343 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 459, 629, 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 459, 629, 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 459, 629, 343 is 1.
HCF(459, 629, 343) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 459, 629, 343 is 1.
Step 1: Since 629 > 459, we apply the division lemma to 629 and 459, to get
629 = 459 x 1 + 170
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 170 and 459, to get
459 = 170 x 2 + 119
Step 3: We consider the new divisor 170 and the new remainder 119, and apply the division lemma to get
170 = 119 x 1 + 51
We consider the new divisor 119 and the new remainder 51,and apply the division lemma to get
119 = 51 x 2 + 17
We consider the new divisor 51 and the new remainder 17,and apply the division lemma to get
51 = 17 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 459 and 629 is 17
Notice that 17 = HCF(51,17) = HCF(119,51) = HCF(170,119) = HCF(459,170) = HCF(629,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 343 > 17, we apply the division lemma to 343 and 17, to get
343 = 17 x 20 + 3
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 3 and 17, to get
17 = 3 x 5 + 2
Step 3: 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 17 and 343 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(343,17) .
Here are some samples of HCF using Euclid's Algorithm calculations.
