HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 2028 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 831, 2028 is 3 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 831, 2028 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 831, 2028 is 3.

HCF(831, 2028) = 3

Highest Common Factor of 831,2028 using Euclid's algorithm

Highest Common Factor of 831,2028 is 3

Step 1: Since 2028 > 831, we apply the division lemma to 2028 and 831, to get

2028 = 831 x 2 + 366

Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 366 and 831, to get

831 = 366 x 2 + 99

Step 3: We consider the new divisor 366 and the new remainder 99, and apply the division lemma to get

366 = 99 x 3 + 69

We consider the new divisor 99 and the new remainder 69,and apply the division lemma to get

99 = 69 x 1 + 30

We consider the new divisor 69 and the new remainder 30,and apply the division lemma to get

69 = 30 x 2 + 9

We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get

30 = 9 x 3 + 3

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

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 2028 is 3

Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(69,30) = HCF(99,69) = HCF(366,99) = HCF(831,366) = HCF(2028,831) .
