Lets's calculate LCM of 820,244,260

2 820, 244, 260
2 410, 122, 130
5 205, 61, 65
41, 61, 13

∴ So the LCM of the given numbers is 2 x 2 x 5 x 41 x 61 x 13 = 650260

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/650260

Therefore, the GCF of Fractions 13/820,38/244,403/260 is 1/650260

Least Common Multiple of 820,244,260 with GCF Formula

Least Common Multiple of 820,244,260 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 820,244,260 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(820,244,260) = 4

common factors(in case of two or more numbers have common factors) = 20

GCF(820,244,260) x common factors =4 x 20 = 80

LCM(820,244,260) = ( 820 × 244 × 260 ) / 80

LCM(820,244,260) = 52020800 / 80

LCM(820,244,260) = 650260
