HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7840, 7990 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 7840, 7990 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 7840, 7990 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 7840, 7990 is 10.
HCF(7840, 7990) = 10
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7840, 7990 is 10.
Step 1: Since 7990 > 7840, we apply the division lemma to 7990 and 7840, to get
7990 = 7840 x 1 + 150
Step 2: Since the reminder 7840 ≠ 0, we apply division lemma to 150 and 7840, to get
7840 = 150 x 52 + 40
Step 3: We consider the new divisor 150 and the new remainder 40, and apply the division lemma to get
150 = 40 x 3 + 30
We consider the new divisor 40 and the new remainder 30,and apply the division lemma to get
40 = 30 x 1 + 10
We consider the new divisor 30 and the new remainder 10,and apply the division lemma to get
30 = 10 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 7840 and 7990 is 10
Notice that 10 = HCF(30,10) = HCF(40,30) = HCF(150,40) = HCF(7840,150) = HCF(7990,7840) .
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 7840, 7990?
Answer: HCF of 7840, 7990 is 10 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 7840, 7990 using Euclid's Algorithm?
Answer: For arbitrary numbers 7840, 7990 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
