HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 365 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 989, 365 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 989, 365 is 1.
HCF(989, 365) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 989, 365 is 1.
Step 1: Since 989 > 365, we apply the division lemma to 989 and 365, to get
989 = 365 x 2 + 259
Step 2: Since the reminder 365 ≠ 0, we apply division lemma to 259 and 365, to get
365 = 259 x 1 + 106
Step 3: We consider the new divisor 259 and the new remainder 106, and apply the division lemma to get
259 = 106 x 2 + 47
We consider the new divisor 106 and the new remainder 47,and apply the division lemma to get
106 = 47 x 2 + 12
We consider the new divisor 47 and the new remainder 12,and apply the division lemma to get
47 = 12 x 3 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 365 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(47,12) = HCF(106,47) = HCF(259,106) = HCF(365,259) = HCF(989,365) .
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 989, 365?
Answer: HCF of 989, 365 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 989, 365 using Euclid's Algorithm?
Answer: For arbitrary numbers 989, 365 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
