HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 460, 253, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 460, 253, 145 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 460, 253, 145 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 460, 253, 145 is 1.
HCF(460, 253, 145) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 460, 253, 145 is 1.
Step 1: Since 460 > 253, we apply the division lemma to 460 and 253, to get
460 = 253 x 1 + 207
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 207 and 253, to get
253 = 207 x 1 + 46
Step 3: We consider the new divisor 207 and the new remainder 46, and apply the division lemma to get
207 = 46 x 4 + 23
We consider the new divisor 46 and the new remainder 23, and apply the division lemma to get
46 = 23 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 460 and 253 is 23
Notice that 23 = HCF(46,23) = HCF(207,46) = HCF(253,207) = HCF(460,253) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 23, we apply the division lemma to 145 and 23, to get
145 = 23 x 6 + 7
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 7 and 23, to get
23 = 7 x 3 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 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 23 and 145 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(145,23) .
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 460, 253, 145?
Answer: HCF of 460, 253, 145 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 460, 253, 145 using Euclid's Algorithm?
Answer: For arbitrary numbers 460, 253, 145 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
