HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 25, 15, 46, 468 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 25, 15, 46, 468 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 25, 15, 46, 468 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 25, 15, 46, 468 is 1.
HCF(25, 15, 46, 468) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 25, 15, 46, 468 is 1.
Step 1: Since 25 > 15, we apply the division lemma to 25 and 15, to get
25 = 15 x 1 + 10
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 10 and 15, to get
15 = 10 x 1 + 5
Step 3: 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 25 and 15 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 46 > 5, we apply the division lemma to 46 and 5, to get
46 = 5 x 9 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 46 is 1
Notice that 1 = HCF(5,1) = HCF(46,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 1, we apply the division lemma to 468 and 1, to get
468 = 1 x 468 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 468 is 1
Notice that 1 = HCF(468,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 25, 15, 46, 468?
Answer: HCF of 25, 15, 46, 468 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 25, 15, 46, 468 using Euclid's Algorithm?
Answer: For arbitrary numbers 25, 15, 46, 468 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
