HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 958, 409, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 958, 409, 25 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 958, 409, 25 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 958, 409, 25 is 1.
HCF(958, 409, 25) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 958, 409, 25 is 1.
Step 1: Since 958 > 409, we apply the division lemma to 958 and 409, to get
958 = 409 x 2 + 140
Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 140 and 409, to get
409 = 140 x 2 + 129
Step 3: We consider the new divisor 140 and the new remainder 129, and apply the division lemma to get
140 = 129 x 1 + 11
We consider the new divisor 129 and the new remainder 11,and apply the division lemma to get
129 = 11 x 11 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 958 and 409 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(129,11) = HCF(140,129) = HCF(409,140) = HCF(958,409) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25 > 1, we apply the division lemma to 25 and 1, to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 25 is 1
Notice that 1 = HCF(25,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 958, 409, 25?
Answer: HCF of 958, 409, 25 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 958, 409, 25 using Euclid's Algorithm?
Answer: For arbitrary numbers 958, 409, 25 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
