HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 409 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 409 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 320, 409 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 320, 409 is 1.
HCF(320, 409) = 1
HCF of 320, 409 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 409 is 1.
Highest Common Factor of 320,409 is 1
Step 1: Since 409 > 320, we apply the division lemma to 409 and 320, to get
409 = 320 x 1 + 89
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 89 and 320, to get
320 = 89 x 3 + 53
Step 3: We consider the new divisor 89 and the new remainder 53, and apply the division lemma to get
89 = 53 x 1 + 36
We consider the new divisor 53 and the new remainder 36,and apply the division lemma to get
53 = 36 x 1 + 17
We consider the new divisor 36 and the new remainder 17,and apply the division lemma to get
36 = 17 x 2 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 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 320 and 409 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(36,17) = HCF(53,36) = HCF(89,53) = HCF(320,89) = HCF(409,320) .
