Lets's calculate LCM of 389,602,378
2 | 389, 602, 378 |
7 | 389, 301, 189 |
389, 43, 27 |
∴ So the LCM of the given numbers is 2 x 7 x 389 x 43 x 27 = 6322806
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6322806
Therefore, the GCF of Fractions 79/389,68/602,973/378 is 1/6322806
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 389,602,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,602,378) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(389,602,378) x common factors =1 x 14 = 14
LCM(389,602,378) = ( 389 × 602 × 378 ) / 14
LCM(389,602,378) = 88519284 / 14
LCM(389,602,378) = 6322806
