Lets's calculate LCM of 991,202,774
2 | 991, 202, 774 |
991, 101, 387 |
∴ So the LCM of the given numbers is 2 x 991 x 101 x 387 = 77470434
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/77470434
Therefore, the GCF of Fractions 42/991,68/202,936/774 is 2/77470434
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 991,202,774 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(991,202,774) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(991,202,774) x common factors =1 x 2 = 2
LCM(991,202,774) = ( 991 × 202 × 774 ) / 2
LCM(991,202,774) = 154940868 / 2
LCM(991,202,774) = 77470434
