HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 5635 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 5635 is 7 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 518, 5635 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 518, 5635 is 7.
HCF(518, 5635) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 518, 5635 is 7.
Step 1: Since 5635 > 518, we apply the division lemma to 5635 and 518, to get
5635 = 518 x 10 + 455
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 455 and 518, to get
518 = 455 x 1 + 63
Step 3: We consider the new divisor 455 and the new remainder 63, and apply the division lemma to get
455 = 63 x 7 + 14
We consider the new divisor 63 and the new remainder 14,and apply the division lemma to get
63 = 14 x 4 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 518 and 5635 is 7
Notice that 7 = HCF(14,7) = HCF(63,14) = HCF(455,63) = HCF(518,455) = HCF(5635,518) .
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 518, 5635?
Answer: HCF of 518, 5635 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 518, 5635 using Euclid's Algorithm?
Answer: For arbitrary numbers 518, 5635 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
