Lets's calculate LCM of 988,350,368
2 | 988, 350, 368 |
2 | 494, 175, 184 |
247, 175, 92 |
∴ So the LCM of the given numbers is 2 x 2 x 247 x 175 x 92 = 15906800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15906800
Therefore, the GCF of Fractions 721/988,839/350,918/368 is 1/15906800
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 988,350,368 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(988,350,368) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(988,350,368) x common factors =2 x 4 = 8
LCM(988,350,368) = ( 988 × 350 × 368 ) / 8
LCM(988,350,368) = 127254400 / 8
LCM(988,350,368) = 15906800
