So the greatest common factor 90,94,812 is 2.
Lets's calculate LCM of 72,379,308
2 | 72, 379, 308 |
2 | 36, 379, 154 |
18, 379, 77 |
∴ So the LCM of the given numbers is 2 x 2 x 18 x 379 x 77 = 2101176
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2101176
Therefore, the GCF of Fractions 90/72,94/379,812/308 is 2/2101176
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 72,379,308 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,379,308) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(72,379,308) x common factors =1 x 4 = 4
LCM(72,379,308) = ( 72 × 379 × 308 ) / 4
LCM(72,379,308) = 8404704 / 4
LCM(72,379,308) = 2101176
