Lets's calculate LCM of 782,490
2 | 782, 490 |
391, 245 |
∴ So the LCM of the given numbers is 2 x 391 x 245 = 191590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/191590
Therefore, the GCF of Fractions 1953/782,3974/490 is 1/191590
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 782,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(782,490) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(782,490) x common factors =2 x 1 = 2
LCM(782,490) = ( 782 × 490 ) / 2
LCM(782,490) = 383180 / 2
LCM(782,490) = 191590
