HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 554, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 554, 163 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 554, 163 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 554, 163 is 1.
HCF(554, 163) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 554, 163 is 1.
Step 1: Since 554 > 163, we apply the division lemma to 554 and 163, to get
554 = 163 x 3 + 65
Step 2: Since the reminder 163 ≠ 0, we apply division lemma to 65 and 163, to get
163 = 65 x 2 + 33
Step 3: We consider the new divisor 65 and the new remainder 33, and apply the division lemma to get
65 = 33 x 1 + 32
We consider the new divisor 33 and the new remainder 32,and apply the division lemma to get
33 = 32 x 1 + 1
We consider the new divisor 32 and the new remainder 1,and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 554 and 163 is 1
Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(65,33) = HCF(163,65) = HCF(554,163) .
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 554, 163?
Answer: HCF of 554, 163 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 554, 163 using Euclid's Algorithm?
Answer: For arbitrary numbers 554, 163 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
