HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 660, 280 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 648, 660, 280 is 4 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, 660, 280 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, 660, 280 is 4.
HCF(648, 660, 280) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 648, 660, 280 is 4.
Step 1: Since 660 > 648, we apply the division lemma to 660 and 648, to get
660 = 648 x 1 + 12
Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 12 and 648, to get
648 = 12 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 648 and 660 is 12
Notice that 12 = HCF(648,12) = HCF(660,648) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 280 > 12, we apply the division lemma to 280 and 12, to get
280 = 12 x 23 + 4
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 4 and 12, to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 12 and 280 is 4
Notice that 4 = HCF(12,4) = HCF(280,12) .
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, 660, 280?
Answer: HCF of 648, 660, 280 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 648, 660, 280 using Euclid's Algorithm?
Answer: For arbitrary numbers 648, 660, 280 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
