HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7791, 2810 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 7791, 2810 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 7791, 2810 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 7791, 2810 is 1.

HCF(7791, 2810) = 1

Highest common factor (HCF) of 7791, 2810 is 1.

Highest Common Factor of 7791,2810 using Euclid's algorithm

Highest Common Factor of 7791,2810 is 1

Step 1: Since 7791 > 2810, we apply the division lemma to 7791 and 2810, to get

7791 = 2810 x 2 + 2171

Step 2: Since the reminder 2810 ≠ 0, we apply division lemma to 2171 and 2810, to get

2810 = 2171 x 1 + 639

Step 3: We consider the new divisor 2171 and the new remainder 639, and apply the division lemma to get

2171 = 639 x 3 + 254

We consider the new divisor 639 and the new remainder 254,and apply the division lemma to get

639 = 254 x 2 + 131

We consider the new divisor 254 and the new remainder 131,and apply the division lemma to get

254 = 131 x 1 + 123

We consider the new divisor 131 and the new remainder 123,and apply the division lemma to get

131 = 123 x 1 + 8

We consider the new divisor 123 and the new remainder 8,and apply the division lemma to get

123 = 8 x 15 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 7791 and 2810 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(123,8) = HCF(131,123) = HCF(254,131) = HCF(639,254) = HCF(2171,639) = HCF(2810,2171) = HCF(7791,2810) .
