HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 409, 724, 913 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 409, 724, 913 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 409, 724, 913 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 409, 724, 913 is 1.
HCF(409, 724, 913) = 1
HCF of 409, 724, 913 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 409, 724, 913 is 1.
Highest Common Factor of 409,724,913 is 1
Step 1: Since 724 > 409, we apply the division lemma to 724 and 409, to get
724 = 409 x 1 + 315
Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 315 and 409, to get
409 = 315 x 1 + 94
Step 3: We consider the new divisor 315 and the new remainder 94, and apply the division lemma to get
315 = 94 x 3 + 33
We consider the new divisor 94 and the new remainder 33,and apply the division lemma to get
94 = 33 x 2 + 28
We consider the new divisor 33 and the new remainder 28,and apply the division lemma to get
33 = 28 x 1 + 5
We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get
28 = 5 x 5 + 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 409 and 724 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(33,28) = HCF(94,33) = HCF(315,94) = HCF(409,315) = HCF(724,409) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 913 > 1, we apply the division lemma to 913 and 1, to get
913 = 1 x 913 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 913 is 1
Notice that 1 = HCF(913,1) .
