Lets's calculate LCM of 988,285,357
3 | 988, 285, 357 |
19 | 988, 95, 119 |
52, 5, 119 |
∴ So the LCM of the given numbers is 3 x 19 x 52 x 5 x 119 = 1763580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1763580
Therefore, the GCF of Fractions 77/988,87/285,980/357 is 1/1763580
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 988,285,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(988,285,357) = 1
common factors(in case of two or more numbers have common factors) = 57
GCF(988,285,357) x common factors =1 x 57 = 57
LCM(988,285,357) = ( 988 × 285 × 357 ) / 57
LCM(988,285,357) = 100524060 / 57
LCM(988,285,357) = 1763580
