HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 999, 538 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 999, 538 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 999, 538 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 999, 538 is 1.
HCF(999, 538) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 999, 538 is 1.
Step 1: Since 999 > 538, we apply the division lemma to 999 and 538, to get
999 = 538 x 1 + 461
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 461 and 538, to get
538 = 461 x 1 + 77
Step 3: We consider the new divisor 461 and the new remainder 77, and apply the division lemma to get
461 = 77 x 5 + 76
We consider the new divisor 77 and the new remainder 76,and apply the division lemma to get
77 = 76 x 1 + 1
We consider the new divisor 76 and the new remainder 1,and apply the division lemma to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 999 and 538 is 1
Notice that 1 = HCF(76,1) = HCF(77,76) = HCF(461,77) = HCF(538,461) = HCF(999,538) .
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 999, 538?
Answer: HCF of 999, 538 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 999, 538 using Euclid's Algorithm?
Answer: For arbitrary numbers 999, 538 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
