HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 177, 496, 171 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 177, 496, 171 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 177, 496, 171 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 177, 496, 171 is 1.
HCF(177, 496, 171) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 177, 496, 171 is 1.
Step 1: Since 496 > 177, we apply the division lemma to 496 and 177, to get
496 = 177 x 2 + 142
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 142 and 177, to get
177 = 142 x 1 + 35
Step 3: We consider the new divisor 142 and the new remainder 35, and apply the division lemma to get
142 = 35 x 4 + 2
We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get
35 = 2 x 17 + 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 177 and 496 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(142,35) = HCF(177,142) = HCF(496,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 171 > 1, we apply the division lemma to 171 and 1, to get
171 = 1 x 171 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 171 is 1
Notice that 1 = HCF(171,1) .
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 177, 496, 171?
Answer: HCF of 177, 496, 171 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 177, 496, 171 using Euclid's Algorithm?
Answer: For arbitrary numbers 177, 496, 171 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
