HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 648 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 648 is 6 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 870, 648 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 870, 648 is 6.
HCF(870, 648) = 6
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 648 is 6.
Step 1: Since 870 > 648, we apply the division lemma to 870 and 648, to get
870 = 648 x 1 + 222
Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 222 and 648, to get
648 = 222 x 2 + 204
Step 3: We consider the new divisor 222 and the new remainder 204, and apply the division lemma to get
222 = 204 x 1 + 18
We consider the new divisor 204 and the new remainder 18,and apply the division lemma to get
204 = 18 x 11 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 870 and 648 is 6
Notice that 6 = HCF(18,6) = HCF(204,18) = HCF(222,204) = HCF(648,222) = HCF(870,648) .
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 870, 648?
Answer: HCF of 870, 648 is 6 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 870, 648 using Euclid's Algorithm?
Answer: For arbitrary numbers 870, 648 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
