So the greatest common factor 358,990,678 is 2.
Lets's calculate LCM of 56,60,890
| 2 | 56, 60, 890 |
| 2 | 28, 30, 445 |
| 5 | 14, 15, 445 |
| 14, 3, 89 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 14 x 3 x 89 = 74760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/74760
Therefore, the GCF of Fractions 358/56,990/60,678/890 is 2/74760
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 56,60,890 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,60,890) = 2
common factors(in case of two or more numbers have common factors) = 20
GCF(56,60,890) x common factors =2 x 20 = 40
LCM(56,60,890) = ( 56 × 60 × 890 ) / 40
LCM(56,60,890) = 2990400 / 40
LCM(56,60,890) = 74760
