Lets's calculate LCM of 472,124,248
2 | 472, 124, 248 |
2 | 236, 62, 124 |
2 | 118, 31, 62 |
31 | 59, 31, 31 |
59, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 31 x 59 x 1 x 1 = 14632
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/14632
Therefore, the GCF of Fractions 660/472,195/124,144/248 is 3/14632
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 472,124,248 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,124,248) = 4
common factors(in case of two or more numbers have common factors) = 248
GCF(472,124,248) x common factors =4 x 248 = 992
LCM(472,124,248) = ( 472 × 124 × 248 ) / 992
LCM(472,124,248) = 14514944 / 992
LCM(472,124,248) = 14632
