So the greatest common factor 1,42,45,439 is 1.
Lets's calculate LCM of 74,80,583,871
2 | 74, 80, 583, 871 |
37, 40, 583, 871 |
∴ So the LCM of the given numbers is 2 x 37 x 40 x 583 x 871 = 1503067280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1503067280
Therefore, the GCF of Fractions 1/74,42/80,45/583,439/871 is 1/1503067280
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 74,80,583,871 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,80,583,871) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(74,80,583,871) x common factors =1 x 2 = 2
LCM(74,80,583,871) = ( 74 × 80 × 583 × 871 ) / 2
LCM(74,80,583,871) = 3006134560 / 2
LCM(74,80,583,871) = 1503067280
