GCF of 903,351,339 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 20,639,686

LCM of Fractions 20/903,639/351,686/339 is 1461180

2 20, 639, 686
10, 639, 343

∴ So the LCM of the given numbers is 2 x 10 x 639 x 343 = 4383540

Least Common Multiple of 20,639,686 with GCF Formula

Least Common Multiple of 20,639,686 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 20,639,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,639,686) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(20,639,686) x common factors =1 x 2 = 2

LCM(20,639,686) = ( 20 × 639 × 686 ) / 2

LCM(20,639,686) = 8767080 / 2

LCM(20,639,686) = 4383540


Lets's calculate GCF of 903,351,339

3 903, 351, 339
301, 117, 113

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4383540/3

Therefore the LCM of Fractions 20/903,639/351,686/339 is 1461180
