HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 547, 789 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 547, 789 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 547, 789 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 547, 789 is 1.
HCF(547, 789) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 547, 789 is 1.
Step 1: Since 789 > 547, we apply the division lemma to 789 and 547, to get
789 = 547 x 1 + 242
Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 242 and 547, to get
547 = 242 x 2 + 63
Step 3: We consider the new divisor 242 and the new remainder 63, and apply the division lemma to get
242 = 63 x 3 + 53
We consider the new divisor 63 and the new remainder 53,and apply the division lemma to get
63 = 53 x 1 + 10
We consider the new divisor 53 and the new remainder 10,and apply the division lemma to get
53 = 10 x 5 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 547 and 789 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(53,10) = HCF(63,53) = HCF(242,63) = HCF(547,242) = HCF(789,547) .
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 547, 789?
Answer: HCF of 547, 789 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 547, 789 using Euclid's Algorithm?
Answer: For arbitrary numbers 547, 789 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
