So the greatest common factor 39,130,208 is 13.
Lets's calculate LCM of 786,128,227
2 | 786, 128, 227 |
393, 64, 227 |
∴ So the LCM of the given numbers is 2 x 393 x 64 x 227 = 11419008
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/11419008
Therefore, the GCF of Fractions 39/786,130/128,208/227 is 13/11419008
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 786,128,227 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(786,128,227) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(786,128,227) x common factors =1 x 2 = 2
LCM(786,128,227) = ( 786 × 128 × 227 ) / 2
LCM(786,128,227) = 22838016 / 2
LCM(786,128,227) = 11419008
