HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 491, 204 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 400, 491, 204 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 400, 491, 204 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 400, 491, 204 is 1.

HCF(400, 491, 204) = 1

HCF of 400, 491, 204 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 400, 491, 204 is 1.

Highest Common Factor of 400,491,204 using Euclid's algorithm

Highest Common Factor of 400,491,204 is 1

Step 1: Since 491 > 400, we apply the division lemma to 491 and 400, to get

491 = 400 x 1 + 91

Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 91 and 400, to get

400 = 91 x 4 + 36

Step 3: We consider the new divisor 91 and the new remainder 36, and apply the division lemma to get

91 = 36 x 2 + 19

We consider the new divisor 36 and the new remainder 19,and apply the division lemma to get

36 = 19 x 1 + 17

We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get

19 = 17 x 1 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 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 400 and 491 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(36,19) = HCF(91,36) = HCF(400,91) = HCF(491,400) .

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

Step 1: Since 204 > 1, we apply the division lemma to 204 and 1, to get

204 = 1 x 204 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 204 is 1

Notice that 1 = HCF(204,1) .
