Lets's calculate LCM of 422,619,676
2 | 422, 619, 676 |
211, 619, 338 |
∴ So the LCM of the given numbers is 2 x 211 x 619 x 338 = 88291684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/88291684
Therefore, the GCF of Fractions 48/422,129/619,639/676 is 3/88291684
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 422,619,676 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(422,619,676) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(422,619,676) x common factors =1 x 2 = 2
LCM(422,619,676) = ( 422 × 619 × 676 ) / 2
LCM(422,619,676) = 176583368 / 2
LCM(422,619,676) = 88291684
