HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 525, 125, 387 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 525, 125, 387 is 1 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 525, 125, 387 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 525, 125, 387 is 1.
HCF(525, 125, 387) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 525, 125, 387 is 1.
Step 1: Since 525 > 125, we apply the division lemma to 525 and 125, to get
525 = 125 x 4 + 25
Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 25 and 125, to get
125 = 25 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 525 and 125 is 25
Notice that 25 = HCF(125,25) = HCF(525,125) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 387 > 25, we apply the division lemma to 387 and 25, to get
387 = 25 x 15 + 12
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 12 and 25, to get
25 = 12 x 2 + 1
Step 3: We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 25 and 387 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(387,25) .
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 525, 125, 387?
Answer: HCF of 525, 125, 387 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 525, 125, 387 using Euclid's Algorithm?
Answer: For arbitrary numbers 525, 125, 387 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
