HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 401, 662, 695 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 401, 662, 695 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 401, 662, 695 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 401, 662, 695 is 1.
HCF(401, 662, 695) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 401, 662, 695 is 1.
Step 1: Since 662 > 401, we apply the division lemma to 662 and 401, to get
662 = 401 x 1 + 261
Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 261 and 401, to get
401 = 261 x 1 + 140
Step 3: We consider the new divisor 261 and the new remainder 140, and apply the division lemma to get
261 = 140 x 1 + 121
We consider the new divisor 140 and the new remainder 121,and apply the division lemma to get
140 = 121 x 1 + 19
We consider the new divisor 121 and the new remainder 19,and apply the division lemma to get
121 = 19 x 6 + 7
We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get
19 = 7 x 2 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 401 and 662 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(121,19) = HCF(140,121) = HCF(261,140) = HCF(401,261) = HCF(662,401) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 695 > 1, we apply the division lemma to 695 and 1, to get
695 = 1 x 695 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 695 is 1
Notice that 1 = HCF(695,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 401, 662, 695?
Answer: HCF of 401, 662, 695 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 401, 662, 695 using Euclid's Algorithm?
Answer: For arbitrary numbers 401, 662, 695 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
