HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 685 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 685 is 5 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 980, 685 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 980, 685 is 5.
HCF(980, 685) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 685 is 5.
Step 1: Since 980 > 685, we apply the division lemma to 980 and 685, to get
980 = 685 x 1 + 295
Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 295 and 685, to get
685 = 295 x 2 + 95
Step 3: We consider the new divisor 295 and the new remainder 95, and apply the division lemma to get
295 = 95 x 3 + 10
We consider the new divisor 95 and the new remainder 10,and apply the division lemma to get
95 = 10 x 9 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 980 and 685 is 5
Notice that 5 = HCF(10,5) = HCF(95,10) = HCF(295,95) = HCF(685,295) = HCF(980,685) .
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 980, 685?
Answer: HCF of 980, 685 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 980, 685 using Euclid's Algorithm?
Answer: For arbitrary numbers 980, 685 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
