HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 346, 401, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 346, 401, 815 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 346, 401, 815 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 346, 401, 815 is 1.
HCF(346, 401, 815) = 1
HCF of 346, 401, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 346, 401, 815 is 1.
Highest Common Factor of 346,401,815 is 1
Step 1: Since 401 > 346, we apply the division lemma to 401 and 346, to get
401 = 346 x 1 + 55
Step 2: Since the reminder 346 ≠ 0, we apply division lemma to 55 and 346, to get
346 = 55 x 6 + 16
Step 3: We consider the new divisor 55 and the new remainder 16, and apply the division lemma to get
55 = 16 x 3 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 346 and 401 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(55,16) = HCF(346,55) = HCF(401,346) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 1, we apply the division lemma to 815 and 1, to get
815 = 1 x 815 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 815 is 1
Notice that 1 = HCF(815,1) .
