HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 654, 803 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 654, 803 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 497, 654, 803 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 497, 654, 803 is 1.
HCF(497, 654, 803) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 654, 803 is 1.
Step 1: Since 654 > 497, we apply the division lemma to 654 and 497, to get
654 = 497 x 1 + 157
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 157 and 497, to get
497 = 157 x 3 + 26
Step 3: We consider the new divisor 157 and the new remainder 26, and apply the division lemma to get
157 = 26 x 6 + 1
We consider the new divisor 26 and the new remainder 1, and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 654 is 1
Notice that 1 = HCF(26,1) = HCF(157,26) = HCF(497,157) = HCF(654,497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 803 > 1, we apply the division lemma to 803 and 1, to get
803 = 1 x 803 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 803 is 1
Notice that 1 = HCF(803,1) .
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 497, 654, 803?
Answer: HCF of 497, 654, 803 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 497, 654, 803 using Euclid's Algorithm?
Answer: For arbitrary numbers 497, 654, 803 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
