HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 532, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 504, 532, 655 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 504, 532, 655 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 504, 532, 655 is 1.
HCF(504, 532, 655) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 504, 532, 655 is 1.
Step 1: Since 532 > 504, we apply the division lemma to 532 and 504, to get
532 = 504 x 1 + 28
Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 28 and 504, to get
504 = 28 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 504 and 532 is 28
Notice that 28 = HCF(504,28) = HCF(532,504) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 655 > 28, we apply the division lemma to 655 and 28, to get
655 = 28 x 23 + 11
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 11 and 28, to get
28 = 11 x 2 + 6
Step 3: We consider the new divisor 11 and the new remainder 6, and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 28 and 655 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(655,28) .
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 504, 532, 655?
Answer: HCF of 504, 532, 655 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 504, 532, 655 using Euclid's Algorithm?
Answer: For arbitrary numbers 504, 532, 655 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
