HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 250, 635, 75 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 250, 635, 75 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 250, 635, 75 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 250, 635, 75 is 5.
HCF(250, 635, 75) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 250, 635, 75 is 5.
Step 1: Since 635 > 250, we apply the division lemma to 635 and 250, to get
635 = 250 x 2 + 135
Step 2: Since the reminder 250 ≠ 0, we apply division lemma to 135 and 250, to get
250 = 135 x 1 + 115
Step 3: We consider the new divisor 135 and the new remainder 115, and apply the division lemma to get
135 = 115 x 1 + 20
We consider the new divisor 115 and the new remainder 20,and apply the division lemma to get
115 = 20 x 5 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 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 250 and 635 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(115,20) = HCF(135,115) = HCF(250,135) = HCF(635,250) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 75 > 5, we apply the division lemma to 75 and 5, to get
75 = 5 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 75 is 5
Notice that 5 = HCF(75,5) .
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 250, 635, 75?
Answer: HCF of 250, 635, 75 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 250, 635, 75 using Euclid's Algorithm?
Answer: For arbitrary numbers 250, 635, 75 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
