HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 913, 665 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 913, 665 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 913, 665 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 913, 665 is 1.
HCF(913, 665) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 913, 665 is 1.
Step 1: Since 913 > 665, we apply the division lemma to 913 and 665, to get
913 = 665 x 1 + 248
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 248 and 665, to get
665 = 248 x 2 + 169
Step 3: We consider the new divisor 248 and the new remainder 169, and apply the division lemma to get
248 = 169 x 1 + 79
We consider the new divisor 169 and the new remainder 79,and apply the division lemma to get
169 = 79 x 2 + 11
We consider the new divisor 79 and the new remainder 11,and apply the division lemma to get
79 = 11 x 7 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 913 and 665 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(79,11) = HCF(169,79) = HCF(248,169) = HCF(665,248) = HCF(913,665) .
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 913, 665?
Answer: HCF of 913, 665 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 913, 665 using Euclid's Algorithm?
Answer: For arbitrary numbers 913, 665 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
