HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 633, 748, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 633, 748, 393 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 633, 748, 393 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 633, 748, 393 is 1.
HCF(633, 748, 393) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 633, 748, 393 is 1.
Step 1: Since 748 > 633, we apply the division lemma to 748 and 633, to get
748 = 633 x 1 + 115
Step 2: Since the reminder 633 ≠ 0, we apply division lemma to 115 and 633, to get
633 = 115 x 5 + 58
Step 3: We consider the new divisor 115 and the new remainder 58, and apply the division lemma to get
115 = 58 x 1 + 57
We consider the new divisor 58 and the new remainder 57,and apply the division lemma to get
58 = 57 x 1 + 1
We consider the new divisor 57 and the new remainder 1,and apply the division lemma to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 633 and 748 is 1
Notice that 1 = HCF(57,1) = HCF(58,57) = HCF(115,58) = HCF(633,115) = HCF(748,633) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 393 > 1, we apply the division lemma to 393 and 1, to get
393 = 1 x 393 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 393 is 1
Notice that 1 = HCF(393,1) .
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 633, 748, 393?
Answer: HCF of 633, 748, 393 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 633, 748, 393 using Euclid's Algorithm?
Answer: For arbitrary numbers 633, 748, 393 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
