So the greatest common factor 250,655 is 5.
Lets's calculate LCM of 780,312
2 | 780, 312 |
2 | 390, 156 |
3 | 195, 78 |
13 | 65, 26 |
5, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 5 x 2 = 1560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1560
Therefore, the GCF of Fractions 250/780,655/312 is 5/1560
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 780,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,312) = 156
common factors(in case of two or more numbers have common factors) = 1
GCF(780,312) x common factors =156 x 1 = 156
LCM(780,312) = ( 780 × 312 ) / 156
LCM(780,312) = 243360 / 156
LCM(780,312) = 1560
