HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 352, 487, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 352, 487, 629 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 352, 487, 629 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 352, 487, 629 is 1.
HCF(352, 487, 629) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 352, 487, 629 is 1.
Step 1: Since 487 > 352, we apply the division lemma to 487 and 352, to get
487 = 352 x 1 + 135
Step 2: Since the reminder 352 ≠ 0, we apply division lemma to 135 and 352, to get
352 = 135 x 2 + 82
Step 3: We consider the new divisor 135 and the new remainder 82, and apply the division lemma to get
135 = 82 x 1 + 53
We consider the new divisor 82 and the new remainder 53,and apply the division lemma to get
82 = 53 x 1 + 29
We consider the new divisor 53 and the new remainder 29,and apply the division lemma to get
53 = 29 x 1 + 24
We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get
29 = 24 x 1 + 5
We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get
24 = 5 x 4 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 352 and 487 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(53,29) = HCF(82,53) = HCF(135,82) = HCF(352,135) = HCF(487,352) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 629 > 1, we apply the division lemma to 629 and 1, to get
629 = 1 x 629 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 629 is 1
Notice that 1 = HCF(629,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
