HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 989, 713 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 989, 713 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 505, 989, 713 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 505, 989, 713 is 1.
HCF(505, 989, 713) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 989, 713 is 1.
Step 1: Since 989 > 505, we apply the division lemma to 989 and 505, to get
989 = 505 x 1 + 484
Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 484 and 505, to get
505 = 484 x 1 + 21
Step 3: We consider the new divisor 484 and the new remainder 21, and apply the division lemma to get
484 = 21 x 23 + 1
We consider the new divisor 21 and the new remainder 1, and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 505 and 989 is 1
Notice that 1 = HCF(21,1) = HCF(484,21) = HCF(505,484) = HCF(989,505) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 713 > 1, we apply the division lemma to 713 and 1, to get
713 = 1 x 713 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 713 is 1
Notice that 1 = HCF(713,1) .
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 505, 989, 713?
Answer: HCF of 505, 989, 713 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 505, 989, 713 using Euclid's Algorithm?
Answer: For arbitrary numbers 505, 989, 713 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
