Lets's calculate LCM of 7861,8449

LCM of Fractions 7861/400,8449/420 is 9488227/20

7 7861, 8449
1123, 1207

∴ So the LCM of the given numbers is 7 x 1123 x 1207 = 9488227

Least Common Multiple of 7861,8449 with GCF Formula

Least Common Multiple of 7861,8449 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 7861,8449 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7861,8449) = 7

common factors(in case of two or more numbers have common factors) = 1

GCF(7861,8449) x common factors =7 x 1 = 7

LCM(7861,8449) = ( 7861 × 8449 ) / 7

LCM(7861,8449) = 66417589 / 7

LCM(7861,8449) = 9488227


Lets's calculate GCF of 400,420

2 400, 420
2 200, 210
5 100, 105
20, 21

∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9488227/20

Therefore the LCM of Fractions 7861/400,8449/420 is 9488227/20
