HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 907, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 577, 907, 491 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 577, 907, 491 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 577, 907, 491 is 1.
HCF(577, 907, 491) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 577, 907, 491 is 1.
Step 1: Since 907 > 577, we apply the division lemma to 907 and 577, to get
907 = 577 x 1 + 330
Step 2: Since the reminder 577 ≠ 0, we apply division lemma to 330 and 577, to get
577 = 330 x 1 + 247
Step 3: We consider the new divisor 330 and the new remainder 247, and apply the division lemma to get
330 = 247 x 1 + 83
We consider the new divisor 247 and the new remainder 83,and apply the division lemma to get
247 = 83 x 2 + 81
We consider the new divisor 83 and the new remainder 81,and apply the division lemma to get
83 = 81 x 1 + 2
We consider the new divisor 81 and the new remainder 2,and apply the division lemma to get
81 = 2 x 40 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 577 and 907 is 1
Notice that 1 = HCF(2,1) = HCF(81,2) = HCF(83,81) = HCF(247,83) = HCF(330,247) = HCF(577,330) = HCF(907,577) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 491 > 1, we apply the division lemma to 491 and 1, to get
491 = 1 x 491 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 491 is 1
Notice that 1 = HCF(491,1) .
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 577, 907, 491?
Answer: HCF of 577, 907, 491 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 577, 907, 491 using Euclid's Algorithm?
Answer: For arbitrary numbers 577, 907, 491 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
