HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 980, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 298, 980, 915 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 298, 980, 915 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 298, 980, 915 is 1.
HCF(298, 980, 915) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 298, 980, 915 is 1.
Step 1: Since 980 > 298, we apply the division lemma to 980 and 298, to get
980 = 298 x 3 + 86
Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 86 and 298, to get
298 = 86 x 3 + 40
Step 3: We consider the new divisor 86 and the new remainder 40, and apply the division lemma to get
86 = 40 x 2 + 6
We consider the new divisor 40 and the new remainder 6,and apply the division lemma to get
40 = 6 x 6 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 298 and 980 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(40,6) = HCF(86,40) = HCF(298,86) = HCF(980,298) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 915 > 2, we apply the division lemma to 915 and 2, to get
915 = 2 x 457 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 915 is 1
Notice that 1 = HCF(2,1) = HCF(915,2) .
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 298, 980, 915?
Answer: HCF of 298, 980, 915 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 298, 980, 915 using Euclid's Algorithm?
Answer: For arbitrary numbers 298, 980, 915 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
