HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 930, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 830, 930, 989 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 830, 930, 989 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 830, 930, 989 is 1.

HCF(830, 930, 989) = 1

HCF of 830, 930, 989 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 830, 930, 989 is 1.

Highest Common Factor of 830,930,989 using Euclid's algorithm

Highest Common Factor of 830,930,989 is 1

Step 1: Since 930 > 830, we apply the division lemma to 930 and 830, to get

930 = 830 x 1 + 100

Step 2: Since the reminder 830 ≠ 0, we apply division lemma to 100 and 830, to get

830 = 100 x 8 + 30

Step 3: We consider the new divisor 100 and the new remainder 30, and apply the division lemma to get

100 = 30 x 3 + 10

We consider the new divisor 30 and the new remainder 10, and apply the division lemma to get

30 = 10 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 830 and 930 is 10

Notice that 10 = HCF(30,10) = HCF(100,30) = HCF(830,100) = HCF(930,830) .

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

Step 1: Since 989 > 10, we apply the division lemma to 989 and 10, to get

989 = 10 x 98 + 9

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 9 and 10, to get

10 = 9 x 1 + 1

Step 3: We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 989 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(989,10) .
