HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 176, 880, 649 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 176, 880, 649 is 11 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 176, 880, 649 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 176, 880, 649 is 11.
HCF(176, 880, 649) = 11
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 176, 880, 649 is 11.
Step 1: Since 880 > 176, we apply the division lemma to 880 and 176, to get
880 = 176 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 176, the HCF of 176 and 880 is 176
Notice that 176 = HCF(880,176) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 649 > 176, we apply the division lemma to 649 and 176, to get
649 = 176 x 3 + 121
Step 2: Since the reminder 176 ≠ 0, we apply division lemma to 121 and 176, to get
176 = 121 x 1 + 55
Step 3: We consider the new divisor 121 and the new remainder 55, and apply the division lemma to get
121 = 55 x 2 + 11
We consider the new divisor 55 and the new remainder 11, and apply the division lemma to get
55 = 11 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 176 and 649 is 11
Notice that 11 = HCF(55,11) = HCF(121,55) = HCF(176,121) = HCF(649,176) .
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 176, 880, 649?
Answer: HCF of 176, 880, 649 is 11 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 176, 880, 649 using Euclid's Algorithm?
Answer: For arbitrary numbers 176, 880, 649 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
