HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 653, 828 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 989, 653, 828 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, 653, 828 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, 653, 828 is 1.

HCF(989, 653, 828) = 1

Highest common factor (HCF) of 989, 653, 828 is 1.

Highest Common Factor of 989,653,828 using Euclid's algorithm

Highest Common Factor of 989,653,828 is 1

Step 1: Since 989 > 653, we apply the division lemma to 989 and 653, to get

989 = 653 x 1 + 336

Step 2: Since the reminder 653 ≠ 0, we apply division lemma to 336 and 653, to get

653 = 336 x 1 + 317

Step 3: We consider the new divisor 336 and the new remainder 317, and apply the division lemma to get

336 = 317 x 1 + 19

We consider the new divisor 317 and the new remainder 19,and apply the division lemma to get

317 = 19 x 16 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 653 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(317,19) = HCF(336,317) = HCF(653,336) = HCF(989,653) .

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

Step 1: Since 828 > 1, we apply the division lemma to 828 and 1, to get

828 = 1 x 828 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 828 is 1

Notice that 1 = HCF(828,1) .
