HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 615 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 270, 615 is 15 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 270, 615 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 270, 615 is 15.
HCF(270, 615) = 15
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 270, 615 is 15.
Step 1: Since 615 > 270, we apply the division lemma to 615 and 270, to get
615 = 270 x 2 + 75
Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 75 and 270, to get
270 = 75 x 3 + 45
Step 3: We consider the new divisor 75 and the new remainder 45, and apply the division lemma to get
75 = 45 x 1 + 30
We consider the new divisor 45 and the new remainder 30,and apply the division lemma to get
45 = 30 x 1 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 270 and 615 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(75,45) = HCF(270,75) = HCF(615,270) .
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 270, 615?
Answer: HCF of 270, 615 is 15 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 270, 615 using Euclid's Algorithm?
Answer: For arbitrary numbers 270, 615 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
