So the greatest common factor 28,18,859 is 1.
Lets's calculate LCM of 912,350,804
2 | 912, 350, 804 |
2 | 456, 175, 402 |
3 | 228, 175, 201 |
76, 175, 67 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 76 x 175 x 67 = 10693200
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10693200
Therefore, the GCF of Fractions 28/912,18/350,859/804 is 1/10693200
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 912,350,804 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(912,350,804) = 2
common factors(in case of two or more numbers have common factors) = 12
GCF(912,350,804) x common factors =2 x 12 = 24
LCM(912,350,804) = ( 912 × 350 × 804 ) / 24
LCM(912,350,804) = 256636800 / 24
LCM(912,350,804) = 10693200
