So the greatest common factor 27,57,155 is 1.
Lets's calculate LCM of 159,984,840
2 | 159, 984, 840 |
2 | 159, 492, 420 |
2 | 159, 246, 210 |
3 | 159, 123, 105 |
53, 41, 35 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 53 x 41 x 35 = 1825320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1825320
Therefore, the GCF of Fractions 27/159,57/984,155/840 is 1/1825320
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 159,984,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(159,984,840) = 3
common factors(in case of two or more numbers have common factors) = 24
GCF(159,984,840) x common factors =3 x 24 = 72
LCM(159,984,840) = ( 159 × 984 × 840 ) / 72
LCM(159,984,840) = 131423040 / 72
LCM(159,984,840) = 1825320
