HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 144, 522, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 144, 522, 503 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 144, 522, 503 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 144, 522, 503 is 1.
HCF(144, 522, 503) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 144, 522, 503 is 1.
Step 1: Since 522 > 144, we apply the division lemma to 522 and 144, to get
522 = 144 x 3 + 90
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 90 and 144, to get
144 = 90 x 1 + 54
Step 3: We consider the new divisor 90 and the new remainder 54, and apply the division lemma to get
90 = 54 x 1 + 36
We consider the new divisor 54 and the new remainder 36,and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 144 and 522 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(90,54) = HCF(144,90) = HCF(522,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 503 > 18, we apply the division lemma to 503 and 18, to get
503 = 18 x 27 + 17
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 17 and 18, to get
18 = 17 x 1 + 1
Step 3: We consider the new divisor 17 and the new remainder 1, and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 18 and 503 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(503,18) .
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 144, 522, 503?
Answer: HCF of 144, 522, 503 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 144, 522, 503 using Euclid's Algorithm?
Answer: For arbitrary numbers 144, 522, 503 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
