Lets's calculate LCM of 640,983,295
5 | 640, 983, 295 |
128, 983, 59 |
∴ So the LCM of the given numbers is 5 x 128 x 983 x 59 = 37118080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37118080
Therefore, the GCF of Fractions 77/640,97/983,958/295 is 1/37118080
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 640,983,295 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,983,295) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(640,983,295) x common factors =1 x 5 = 5
LCM(640,983,295) = ( 640 × 983 × 295 ) / 5
LCM(640,983,295) = 185590400 / 5
LCM(640,983,295) = 37118080
