Lets's calculate LCM of 154,970
| 2 | 154, 970 |
| 77, 485 |
∴ So the LCM of the given numbers is 2 x 77 x 485 = 74690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/74690
Therefore, the GCF of Fractions 897/154,1581/970 is 3/74690
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 154,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(154,970) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(154,970) x common factors =2 x 1 = 2
LCM(154,970) = ( 154 × 970 ) / 2
LCM(154,970) = 149380 / 2
LCM(154,970) = 74690
