HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 418, 248 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 418, 248 is 2 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 418, 248 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 418, 248 is 2.
HCF(418, 248) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 418, 248 is 2.
Step 1: Since 418 > 248, we apply the division lemma to 418 and 248, to get
418 = 248 x 1 + 170
Step 2: Since the reminder 248 ≠ 0, we apply division lemma to 170 and 248, to get
248 = 170 x 1 + 78
Step 3: We consider the new divisor 170 and the new remainder 78, and apply the division lemma to get
170 = 78 x 2 + 14
We consider the new divisor 78 and the new remainder 14,and apply the division lemma to get
78 = 14 x 5 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 418 and 248 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(78,14) = HCF(170,78) = HCF(248,170) = HCF(418,248) .
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 418, 248?
Answer: HCF of 418, 248 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 418, 248 using Euclid's Algorithm?
Answer: For arbitrary numbers 418, 248 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
