Lets's calculate LCM of 16,28,240
2 | 16, 28, 240 |
2 | 8, 14, 120 |
2 | 4, 7, 60 |
2 | 2, 7, 30 |
1, 7, 15 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 1 x 7 x 15 = 1680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1680
Therefore, the GCF of Fractions 72/16,930/28,308/240 is 2/1680
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 16,28,240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,28,240) = 4
common factors(in case of two or more numbers have common factors) = 16
GCF(16,28,240) x common factors =4 x 16 = 64
LCM(16,28,240) = ( 16 × 28 × 240 ) / 64
LCM(16,28,240) = 107520 / 64
LCM(16,28,240) = 1680
