HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 325, 768, 130 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 325, 768, 130 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 325, 768, 130 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 325, 768, 130 is 1.
HCF(325, 768, 130) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 325, 768, 130 is 1.
Step 1: Since 768 > 325, we apply the division lemma to 768 and 325, to get
768 = 325 x 2 + 118
Step 2: Since the reminder 325 ≠ 0, we apply division lemma to 118 and 325, to get
325 = 118 x 2 + 89
Step 3: We consider the new divisor 118 and the new remainder 89, and apply the division lemma to get
118 = 89 x 1 + 29
We consider the new divisor 89 and the new remainder 29,and apply the division lemma to get
89 = 29 x 3 + 2
We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get
29 = 2 x 14 + 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 325 and 768 is 1
Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(89,29) = HCF(118,89) = HCF(325,118) = HCF(768,325) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 1, we apply the division lemma to 130 and 1, to get
130 = 1 x 130 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 130 is 1
Notice that 1 = HCF(130,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 325, 768, 130?
Answer: HCF of 325, 768, 130 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 325, 768, 130 using Euclid's Algorithm?
Answer: For arbitrary numbers 325, 768, 130 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
