HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 218, 73 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 218, 73 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 218, 73 is 1.
HCF(218, 73) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 218, 73 is 1.
Step 1: Since 218 > 73, we apply the division lemma to 218 and 73, to get
218 = 73 x 2 + 72
Step 2: Since the reminder 73 ≠ 0, we apply division lemma to 72 and 73, to get
73 = 72 x 1 + 1
Step 3: We consider the new divisor 72 and the new remainder 1, and apply the division lemma to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 218 and 73 is 1
Notice that 1 = HCF(72,1) = HCF(73,72) = HCF(218,73) .
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 218, 73?
Answer: HCF of 218, 73 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 218, 73 using Euclid's Algorithm?
Answer: For arbitrary numbers 218, 73 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
