HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 335, 263 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 990, 335, 263 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 990, 335, 263 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 990, 335, 263 is 1.

HCF(990, 335, 263) = 1

HCF of 990, 335, 263 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 990, 335, 263 is 1.

Highest Common Factor of 990,335,263 using Euclid's algorithm

Highest Common Factor of 990,335,263 is 1

Step 1: Since 990 > 335, we apply the division lemma to 990 and 335, to get

990 = 335 x 2 + 320

Step 2: Since the reminder 335 ≠ 0, we apply division lemma to 320 and 335, to get

335 = 320 x 1 + 15

Step 3: We consider the new divisor 320 and the new remainder 15, and apply the division lemma to get

320 = 15 x 21 + 5

We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 990 and 335 is 5

Notice that 5 = HCF(15,5) = HCF(320,15) = HCF(335,320) = HCF(990,335) .

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

Step 1: Since 263 > 5, we apply the division lemma to 263 and 5, to get

263 = 5 x 52 + 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 263 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(263,5) .
