HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 400, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 484, 400, 243 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 484, 400, 243 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 484, 400, 243 is 1.

HCF(484, 400, 243) = 1

HCF of 484, 400, 243 using Euclid's algorithm

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

Highest common factor (HCF) of 484, 400, 243 is 1.

Highest Common Factor of 484,400,243 using Euclid's algorithm

Highest Common Factor of 484,400,243 is 1

Step 1: Since 484 > 400, we apply the division lemma to 484 and 400, to get

484 = 400 x 1 + 84

Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 84 and 400, to get

400 = 84 x 4 + 64

Step 3: We consider the new divisor 84 and the new remainder 64, and apply the division lemma to get

84 = 64 x 1 + 20

We consider the new divisor 64 and the new remainder 20,and apply the division lemma to get

64 = 20 x 3 + 4

We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 484 and 400 is 4

Notice that 4 = HCF(20,4) = HCF(64,20) = HCF(84,64) = HCF(400,84) = HCF(484,400) .

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

Step 1: Since 243 > 4, we apply the division lemma to 243 and 4, to get

243 = 4 x 60 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 243 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(243,4) .
