HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 239, 344, 990 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 239, 344, 990 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 239, 344, 990 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 239, 344, 990 is 1.

HCF(239, 344, 990) = 1

Highest common factor (HCF) of 239, 344, 990 is 1.

Highest Common Factor of 239,344,990 using Euclid's algorithm

Highest Common Factor of 239,344,990 is 1

Step 1: Since 344 > 239, we apply the division lemma to 344 and 239, to get

344 = 239 x 1 + 105

Step 2: Since the reminder 239 ≠ 0, we apply division lemma to 105 and 239, to get

239 = 105 x 2 + 29

Step 3: We consider the new divisor 105 and the new remainder 29, and apply the division lemma to get

105 = 29 x 3 + 18

We consider the new divisor 29 and the new remainder 18,and apply the division lemma to get

29 = 18 x 1 + 11

We consider the new divisor 18 and the new remainder 11,and apply the division lemma to get

18 = 11 x 1 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

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 239 and 344 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(29,18) = HCF(105,29) = HCF(239,105) = HCF(344,239) .

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

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

990 = 1 x 990 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 990 is 1

Notice that 1 = HCF(990,1) .
