Lets's calculate LCM of 984,2775

Lowest Common Multiple of 984,2775 using Common Division

3	984, 2775
	328, 925

∴ So the LCM of the given numbers is 3 x 328 x 925 = 910200

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/910200

Therefore, the GCF of Fractions 21/984,22/2775 is 1/910200

Least Common Multiple of 984,2775 with GCF Formula

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

We need to calculate greatest common factor of 984,2775 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(984,2775) = 3

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

GCF(984,2775) x common factors =3 x 1 = 3

LCM(984,2775) = ( 984 × 2775 ) / 3

LCM(984,2775) = 2730600 / 3

LCM(984,2775) = 910200
