HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 791, 913 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 504, 791, 913 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 504, 791, 913 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 504, 791, 913 is 1.
HCF(504, 791, 913) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 504, 791, 913 is 1.
Step 1: Since 791 > 504, we apply the division lemma to 791 and 504, to get
791 = 504 x 1 + 287
Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 287 and 504, to get
504 = 287 x 1 + 217
Step 3: We consider the new divisor 287 and the new remainder 217, and apply the division lemma to get
287 = 217 x 1 + 70
We consider the new divisor 217 and the new remainder 70,and apply the division lemma to get
217 = 70 x 3 + 7
We consider the new divisor 70 and the new remainder 7,and apply the division lemma to get
70 = 7 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 504 and 791 is 7
Notice that 7 = HCF(70,7) = HCF(217,70) = HCF(287,217) = HCF(504,287) = HCF(791,504) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 913 > 7, we apply the division lemma to 913 and 7, to get
913 = 7 x 130 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: 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 7 and 913 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(913,7) .
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 504, 791, 913?
Answer: HCF of 504, 791, 913 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 504, 791, 913 using Euclid's Algorithm?
Answer: For arbitrary numbers 504, 791, 913 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
