HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 5655 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 5655 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 615, 5655 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 615, 5655 is 15.
HCF(615, 5655) = 15
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 5655 is 15.
Step 1: Since 5655 > 615, we apply the division lemma to 5655 and 615, to get
5655 = 615 x 9 + 120
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 120 and 615, to get
615 = 120 x 5 + 15
Step 3: We consider the new divisor 120 and the new remainder 15, and apply the division lemma to get
120 = 15 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 615 and 5655 is 15
Notice that 15 = HCF(120,15) = HCF(615,120) = HCF(5655,615) .
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 615, 5655?
Answer: HCF of 615, 5655 is 15 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 615, 5655 using Euclid's Algorithm?
Answer: For arbitrary numbers 615, 5655 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
