HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 40, 225, 363 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 40, 225, 363 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 40, 225, 363 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 40, 225, 363 is 1.

HCF(40, 225, 363) = 1

HCF of 40, 225, 363 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 40, 225, 363 is 1.

Highest Common Factor of 40,225,363 using Euclid's algorithm

Highest Common Factor of 40,225,363 is 1

Step 1: Since 225 > 40, we apply the division lemma to 225 and 40, to get

225 = 40 x 5 + 25

Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 25 and 40, to get

40 = 25 x 1 + 15

Step 3: We consider the new divisor 25 and the new remainder 15, and apply the division lemma to get

25 = 15 x 1 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 40 and 225 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(40,25) = HCF(225,40) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 363 > 5, we apply the division lemma to 363 and 5, to get

363 = 5 x 72 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 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 5 and 363 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(363,5) .
