HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 732, 251, 576, 40 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 732, 251, 576, 40 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 732, 251, 576, 40 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 732, 251, 576, 40 is 1.
HCF(732, 251, 576, 40) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 732, 251, 576, 40 is 1.
Step 1: Since 732 > 251, we apply the division lemma to 732 and 251, to get
732 = 251 x 2 + 230
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 230 and 251, to get
251 = 230 x 1 + 21
Step 3: We consider the new divisor 230 and the new remainder 21, and apply the division lemma to get
230 = 21 x 10 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 732 and 251 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(230,21) = HCF(251,230) = HCF(732,251) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 576 > 1, we apply the division lemma to 576 and 1, to get
576 = 1 x 576 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 576 is 1
Notice that 1 = HCF(576,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 1, we apply the division lemma to 40 and 1, to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 40 is 1
Notice that 1 = HCF(40,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 732, 251, 576, 40?
Answer: HCF of 732, 251, 576, 40 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 732, 251, 576, 40 using Euclid's Algorithm?
Answer: For arbitrary numbers 732, 251, 576, 40 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
