HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 523, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 523, 55 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 523, 55 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 523, 55 is 1.
HCF(523, 55) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 523, 55 is 1.
Step 1: Since 523 > 55, we apply the division lemma to 523 and 55, to get
523 = 55 x 9 + 28
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 28 and 55, to get
55 = 28 x 1 + 27
Step 3: We consider the new divisor 28 and the new remainder 27, and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1, and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 523 and 55 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(55,28) = HCF(523,55) .
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 523, 55?
Answer: HCF of 523, 55 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 523, 55 using Euclid's Algorithm?
Answer: For arbitrary numbers 523, 55 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
