Greatest Common Factor
We found the factors 60,79,455 . The biggest common factor number is the GCF number.
So the greatest common factor 60,79,455 is 1.
Lets's calculate LCM of 11,247,208
13 | 11, 247, 208 |
11, 19, 16 |
∴ So the LCM of the given numbers is 13 x 11 x 19 x 16 = 43472
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/43472
Therefore, the GCF of Fractions 60/11,79/247,455/208 is 1/43472
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 11,247,208 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,247,208) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(11,247,208) x common factors =1 x 13 = 13
LCM(11,247,208) = ( 11 × 247 × 208 ) / 13
LCM(11,247,208) = 565136 / 13
LCM(11,247,208) = 43472
