HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 408, 38 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 741, 408, 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 741, 408, 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 741, 408, 38 is 1.
HCF(741, 408, 38) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 741, 408, 38 is 1.
Step 1: Since 741 > 408, we apply the division lemma to 741 and 408, to get
741 = 408 x 1 + 333
Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 333 and 408, to get
408 = 333 x 1 + 75
Step 3: We consider the new divisor 333 and the new remainder 75, and apply the division lemma to get
333 = 75 x 4 + 33
We consider the new divisor 75 and the new remainder 33,and apply the division lemma to get
75 = 33 x 2 + 9
We consider the new divisor 33 and the new remainder 9,and apply the division lemma to get
33 = 9 x 3 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 741 and 408 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(33,9) = HCF(75,33) = HCF(333,75) = HCF(408,333) = HCF(741,408) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 3, we apply the division lemma to 38 and 3, to get
38 = 3 x 12 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 38 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) .
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 741, 408, 38?
Answer: HCF of 741, 408, 38 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 741, 408, 38 using Euclid's Algorithm?
Answer: For arbitrary numbers 741, 408, 38 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
