HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 409, 313 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 409, 313 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 571, 409, 313 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 571, 409, 313 is 1.
HCF(571, 409, 313) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 571, 409, 313 is 1.
Step 1: Since 571 > 409, we apply the division lemma to 571 and 409, to get
571 = 409 x 1 + 162
Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 162 and 409, to get
409 = 162 x 2 + 85
Step 3: We consider the new divisor 162 and the new remainder 85, and apply the division lemma to get
162 = 85 x 1 + 77
We consider the new divisor 85 and the new remainder 77,and apply the division lemma to get
85 = 77 x 1 + 8
We consider the new divisor 77 and the new remainder 8,and apply the division lemma to get
77 = 8 x 9 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 571 and 409 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(77,8) = HCF(85,77) = HCF(162,85) = HCF(409,162) = HCF(571,409) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 313 > 1, we apply the division lemma to 313 and 1, to get
313 = 1 x 313 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 313 is 1
Notice that 1 = HCF(313,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
