HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 611, 111, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 611, 111, 247 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 611, 111, 247 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 611, 111, 247 is 1.
HCF(611, 111, 247) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 611, 111, 247 is 1.
Step 1: Since 611 > 111, we apply the division lemma to 611 and 111, to get
611 = 111 x 5 + 56
Step 2: Since the reminder 111 ≠ 0, we apply division lemma to 56 and 111, to get
111 = 56 x 1 + 55
Step 3: We consider the new divisor 56 and the new remainder 55, and apply the division lemma to get
56 = 55 x 1 + 1
We consider the new divisor 55 and the new remainder 1, and apply the division lemma to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 611 and 111 is 1
Notice that 1 = HCF(55,1) = HCF(56,55) = HCF(111,56) = HCF(611,111) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 1, we apply the division lemma to 247 and 1, to get
247 = 1 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 247 is 1
Notice that 1 = HCF(247,1) .
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 611, 111, 247?
Answer: HCF of 611, 111, 247 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 611, 111, 247 using Euclid's Algorithm?
Answer: For arbitrary numbers 611, 111, 247 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
