HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 190, 225 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 190, 225 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 190, 225 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 190, 225 is 5.
HCF(190, 225) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 190, 225 is 5.
Step 1: Since 225 > 190, we apply the division lemma to 225 and 190, to get
225 = 190 x 1 + 35
Step 2: Since the reminder 190 ≠ 0, we apply division lemma to 35 and 190, to get
190 = 35 x 5 + 15
Step 3: We consider the new divisor 35 and the new remainder 15, and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 190 and 225 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(190,35) = HCF(225,190) .
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 190, 225?
Answer: HCF of 190, 225 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 190, 225 using Euclid's Algorithm?
Answer: For arbitrary numbers 190, 225 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
