Lets's calculate LCM of 643,534,820
2 | 643, 534, 820 |
643, 267, 410 |
∴ So the LCM of the given numbers is 2 x 643 x 267 x 410 = 140778420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/140778420
Therefore, the GCF of Fractions 960/643,357/534,855/820 is 3/140778420
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 643,534,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,534,820) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(643,534,820) x common factors =1 x 2 = 2
LCM(643,534,820) = ( 643 × 534 × 820 ) / 2
LCM(643,534,820) = 281556840 / 2
LCM(643,534,820) = 140778420
