HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 345, 186 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 345, 186 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 625, 345, 186 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, 345, 186 is 1.
HCF(625, 345, 186) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 345, 186 is 1.
Step 1: Since 625 > 345, we apply the division lemma to 625 and 345, to get
625 = 345 x 1 + 280
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 280 and 345, to get
345 = 280 x 1 + 65
Step 3: We consider the new divisor 280 and the new remainder 65, and apply the division lemma to get
280 = 65 x 4 + 20
We consider the new divisor 65 and the new remainder 20,and apply the division lemma to get
65 = 20 x 3 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 625 and 345 is 5
Notice that 5 = HCF(20,5) = HCF(65,20) = HCF(280,65) = HCF(345,280) = HCF(625,345) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 186 > 5, we apply the division lemma to 186 and 5, to get
186 = 5 x 37 + 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 186 is 1
Notice that 1 = HCF(5,1) = HCF(186,5) .
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, 345, 186?
Answer: HCF of 625, 345, 186 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 625, 345, 186 using Euclid's Algorithm?
Answer: For arbitrary numbers 625, 345, 186 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
