HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 241, 620, 480 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 241, 620, 480 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 241, 620, 480 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 241, 620, 480 is 1.
HCF(241, 620, 480) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 241, 620, 480 is 1.
Step 1: Since 620 > 241, we apply the division lemma to 620 and 241, to get
620 = 241 x 2 + 138
Step 2: Since the reminder 241 ≠ 0, we apply division lemma to 138 and 241, to get
241 = 138 x 1 + 103
Step 3: We consider the new divisor 138 and the new remainder 103, and apply the division lemma to get
138 = 103 x 1 + 35
We consider the new divisor 103 and the new remainder 35,and apply the division lemma to get
103 = 35 x 2 + 33
We consider the new divisor 35 and the new remainder 33,and apply the division lemma to get
35 = 33 x 1 + 2
We consider the new divisor 33 and the new remainder 2,and apply the division lemma to get
33 = 2 x 16 + 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 241 and 620 is 1
Notice that 1 = HCF(2,1) = HCF(33,2) = HCF(35,33) = HCF(103,35) = HCF(138,103) = HCF(241,138) = HCF(620,241) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 1, we apply the division lemma to 480 and 1, to get
480 = 1 x 480 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 480 is 1
Notice that 1 = HCF(480,1) .
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 241, 620, 480?
Answer: HCF of 241, 620, 480 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 241, 620, 480 using Euclid's Algorithm?
Answer: For arbitrary numbers 241, 620, 480 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
