HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 650, 245 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 650, 245 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 650, 245 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 650, 245 is 5.
HCF(650, 245) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 650, 245 is 5.
Step 1: Since 650 > 245, we apply the division lemma to 650 and 245, to get
650 = 245 x 2 + 160
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 160 and 245, to get
245 = 160 x 1 + 85
Step 3: We consider the new divisor 160 and the new remainder 85, and apply the division lemma to get
160 = 85 x 1 + 75
We consider the new divisor 85 and the new remainder 75,and apply the division lemma to get
85 = 75 x 1 + 10
We consider the new divisor 75 and the new remainder 10,and apply the division lemma to get
75 = 10 x 7 + 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 650 and 245 is 5
Notice that 5 = HCF(10,5) = HCF(75,10) = HCF(85,75) = HCF(160,85) = HCF(245,160) = HCF(650,245) .
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 650, 245?
Answer: HCF of 650, 245 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 650, 245 using Euclid's Algorithm?
Answer: For arbitrary numbers 650, 245 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
