So the greatest common factor 30,94,442 is 2.
Lets's calculate LCM of 998,372,356
2 | 998, 372, 356 |
2 | 499, 186, 178 |
499, 93, 89 |
∴ So the LCM of the given numbers is 2 x 2 x 499 x 93 x 89 = 16520892
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/16520892
Therefore, the GCF of Fractions 30/998,94/372,442/356 is 2/16520892
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 998,372,356 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(998,372,356) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(998,372,356) x common factors =2 x 4 = 8
LCM(998,372,356) = ( 998 × 372 × 356 ) / 8
LCM(998,372,356) = 132167136 / 8
LCM(998,372,356) = 16520892
