HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 288 i.e. 72 the largest integer that leaves a remainder zero for all numbers.
HCF of 648, 288 is 72 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 648, 288 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 648, 288 is 72.
HCF(648, 288) = 72
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 648, 288 is 72.
Step 1: Since 648 > 288, we apply the division lemma to 648 and 288, to get
648 = 288 x 2 + 72
Step 2: Since the reminder 288 ≠ 0, we apply division lemma to 72 and 288, to get
288 = 72 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 72, the HCF of 648 and 288 is 72
Notice that 72 = HCF(288,72) = HCF(648,288) .
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 648, 288?
Answer: HCF of 648, 288 is 72 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 648, 288 using Euclid's Algorithm?
Answer: For arbitrary numbers 648, 288 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
