HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 502, 780, 459 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 502, 780, 459 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 502, 780, 459 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 502, 780, 459 is 1.
HCF(502, 780, 459) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 502, 780, 459 is 1.
Step 1: Since 780 > 502, we apply the division lemma to 780 and 502, to get
780 = 502 x 1 + 278
Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 278 and 502, to get
502 = 278 x 1 + 224
Step 3: We consider the new divisor 278 and the new remainder 224, and apply the division lemma to get
278 = 224 x 1 + 54
We consider the new divisor 224 and the new remainder 54,and apply the division lemma to get
224 = 54 x 4 + 8
We consider the new divisor 54 and the new remainder 8,and apply the division lemma to get
54 = 8 x 6 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 502 and 780 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(54,8) = HCF(224,54) = HCF(278,224) = HCF(502,278) = HCF(780,502) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 459 > 2, we apply the division lemma to 459 and 2, to get
459 = 2 x 229 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 459 is 1
Notice that 1 = HCF(2,1) = HCF(459,2) .
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 502, 780, 459?
Answer: HCF of 502, 780, 459 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 502, 780, 459 using Euclid's Algorithm?
Answer: For arbitrary numbers 502, 780, 459 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
