HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 375, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 375, 811 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 240, 375, 811 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 240, 375, 811 is 1.
HCF(240, 375, 811) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 375, 811 is 1.
Step 1: Since 375 > 240, we apply the division lemma to 375 and 240, to get
375 = 240 x 1 + 135
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 135 and 240, to get
240 = 135 x 1 + 105
Step 3: We consider the new divisor 135 and the new remainder 105, and apply the division lemma to get
135 = 105 x 1 + 30
We consider the new divisor 105 and the new remainder 30,and apply the division lemma to get
105 = 30 x 3 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 240 and 375 is 15
Notice that 15 = HCF(30,15) = HCF(105,30) = HCF(135,105) = HCF(240,135) = HCF(375,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 811 > 15, we apply the division lemma to 811 and 15, to get
811 = 15 x 54 + 1
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 1 and 15, to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 811 is 1
Notice that 1 = HCF(15,1) = HCF(811,15) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 240, 375, 811?
Answer: HCF of 240, 375, 811 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 240, 375, 811 using Euclid's Algorithm?
Answer: For arbitrary numbers 240, 375, 811 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
