HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 180, 710 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 30, 180, 710 is 10 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 30, 180, 710 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 30, 180, 710 is 10.
HCF(30, 180, 710) = 10
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 30, 180, 710 is 10.
Step 1: Since 180 > 30, we apply the division lemma to 180 and 30, to get
180 = 30 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 30 and 180 is 30
Notice that 30 = HCF(180,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 710 > 30, we apply the division lemma to 710 and 30, to get
710 = 30 x 23 + 20
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 20 and 30, to get
30 = 20 x 1 + 10
Step 3: We consider the new divisor 20 and the new remainder 10, and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 30 and 710 is 10
Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(710,30) .
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 30, 180, 710?
Answer: HCF of 30, 180, 710 is 10 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 30, 180, 710 using Euclid's Algorithm?
Answer: For arbitrary numbers 30, 180, 710 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
