HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 798, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 989, 798, 884 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 989, 798, 884 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 989, 798, 884 is 1.

HCF(989, 798, 884) = 1

Highest common factor (HCF) of 989, 798, 884 is 1.

Highest Common Factor of 989,798,884 using Euclid's algorithm

Highest Common Factor of 989,798,884 is 1

Step 1: Since 989 > 798, we apply the division lemma to 989 and 798, to get

989 = 798 x 1 + 191

Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 191 and 798, to get

798 = 191 x 4 + 34

Step 3: We consider the new divisor 191 and the new remainder 34, and apply the division lemma to get

191 = 34 x 5 + 21

We consider the new divisor 34 and the new remainder 21,and apply the division lemma to get

34 = 21 x 1 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

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 989 and 798 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(191,34) = HCF(798,191) = HCF(989,798) .

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

Step 1: Since 884 > 1, we apply the division lemma to 884 and 1, to get

884 = 1 x 884 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 884 is 1

Notice that 1 = HCF(884,1) .
