HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 696, 38 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 696, 38 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 451, 696, 38 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 451, 696, 38 is 1.
HCF(451, 696, 38) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 451, 696, 38 is 1.
Step 1: Since 696 > 451, we apply the division lemma to 696 and 451, to get
696 = 451 x 1 + 245
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 245 and 451, to get
451 = 245 x 1 + 206
Step 3: We consider the new divisor 245 and the new remainder 206, and apply the division lemma to get
245 = 206 x 1 + 39
We consider the new divisor 206 and the new remainder 39,and apply the division lemma to get
206 = 39 x 5 + 11
We consider the new divisor 39 and the new remainder 11,and apply the division lemma to get
39 = 11 x 3 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 451 and 696 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(39,11) = HCF(206,39) = HCF(245,206) = HCF(451,245) = HCF(696,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 1, we apply the division lemma to 38 and 1, to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 38 is 1
Notice that 1 = HCF(38,1) .
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 451, 696, 38?
Answer: HCF of 451, 696, 38 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 451, 696, 38 using Euclid's Algorithm?
Answer: For arbitrary numbers 451, 696, 38 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
