HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 240, 130 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 240, 130 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 625, 240, 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 625, 240, 130 is 5.
HCF(625, 240, 130) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 240, 130 is 5.
Step 1: Since 625 > 240, we apply the division lemma to 625 and 240, to get
625 = 240 x 2 + 145
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 145 and 240, to get
240 = 145 x 1 + 95
Step 3: We consider the new divisor 145 and the new remainder 95, and apply the division lemma to get
145 = 95 x 1 + 50
We consider the new divisor 95 and the new remainder 50,and apply the division lemma to get
95 = 50 x 1 + 45
We consider the new divisor 50 and the new remainder 45,and apply the division lemma to get
50 = 45 x 1 + 5
We consider the new divisor 45 and the new remainder 5,and apply the division lemma to get
45 = 5 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 625 and 240 is 5
Notice that 5 = HCF(45,5) = HCF(50,45) = HCF(95,50) = HCF(145,95) = HCF(240,145) = HCF(625,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 5, we apply the division lemma to 130 and 5, to get
130 = 5 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 130 is 5
Notice that 5 = HCF(130,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 625, 240, 130?
Answer: HCF of 625, 240, 130 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 625, 240, 130 using Euclid's Algorithm?
Answer: For arbitrary numbers 625, 240, 130 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
