HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 396, 655 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 396, 655 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 396, 655 is 1.
HCF(396, 655) = 1
HCF of 396, 655 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 396, 655 is 1.
Highest Common Factor of 396,655 is 1
Step 1: Since 655 > 396, we apply the division lemma to 655 and 396, to get
655 = 396 x 1 + 259
Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 259 and 396, to get
396 = 259 x 1 + 137
Step 3: We consider the new divisor 259 and the new remainder 137, and apply the division lemma to get
259 = 137 x 1 + 122
We consider the new divisor 137 and the new remainder 122,and apply the division lemma to get
137 = 122 x 1 + 15
We consider the new divisor 122 and the new remainder 15,and apply the division lemma to get
122 = 15 x 8 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 396 and 655 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(122,15) = HCF(137,122) = HCF(259,137) = HCF(396,259) = HCF(655,396) .
