HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 448, 825 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 448, 825 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 68, 448, 825 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 68, 448, 825 is 1.
HCF(68, 448, 825) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 448, 825 is 1.
Step 1: Since 448 > 68, we apply the division lemma to 448 and 68, to get
448 = 68 x 6 + 40
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 40 and 68, to get
68 = 40 x 1 + 28
Step 3: We consider the new divisor 40 and the new remainder 28, and apply the division lemma to get
40 = 28 x 1 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 68 and 448 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(40,28) = HCF(68,40) = HCF(448,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 825 > 4, we apply the division lemma to 825 and 4, to get
825 = 4 x 206 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 825 is 1
Notice that 1 = HCF(4,1) = HCF(825,4) .
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 68, 448, 825?
Answer: HCF of 68, 448, 825 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 68, 448, 825 using Euclid's Algorithm?
Answer: For arbitrary numbers 68, 448, 825 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
