So the greatest common factor 545,670,399 is 1.
Lets's calculate LCM of 287,946,665
7 | 287, 946, 665 |
41, 946, 95 |
∴ So the LCM of the given numbers is 7 x 41 x 946 x 95 = 25792690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25792690
Therefore, the GCF of Fractions 545/287,670/946,399/665 is 1/25792690
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 287,946,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(287,946,665) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(287,946,665) x common factors =1 x 7 = 7
LCM(287,946,665) = ( 287 × 946 × 665 ) / 7
LCM(287,946,665) = 180548830 / 7
LCM(287,946,665) = 25792690
