HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 989, 829 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 842, 989, 829 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 842, 989, 829 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 842, 989, 829 is 1.

HCF(842, 989, 829) = 1

Highest common factor (HCF) of 842, 989, 829 is 1.

Highest Common Factor of 842,989,829 using Euclid's algorithm

Highest Common Factor of 842,989,829 is 1

Step 1: Since 989 > 842, we apply the division lemma to 989 and 842, to get

989 = 842 x 1 + 147

Step 2: Since the reminder 842 ≠ 0, we apply division lemma to 147 and 842, to get

842 = 147 x 5 + 107

Step 3: We consider the new divisor 147 and the new remainder 107, and apply the division lemma to get

147 = 107 x 1 + 40

We consider the new divisor 107 and the new remainder 40,and apply the division lemma to get

107 = 40 x 2 + 27

We consider the new divisor 40 and the new remainder 27,and apply the division lemma to get

40 = 27 x 1 + 13

We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get

27 = 13 x 2 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 842 and 989 is 1

Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(40,27) = HCF(107,40) = HCF(147,107) = HCF(842,147) = HCF(989,842) .

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

Step 1: Since 829 > 1, we apply the division lemma to 829 and 1, to get

829 = 1 x 829 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 829 is 1

Notice that 1 = HCF(829,1) .
