Greatest Common Factor
We found the factors 97,83,989 . The biggest common factor number is the GCF number.
So the greatest common factor 97,83,989 is 1.
Lets's calculate LCM of 79,40,902
2 | 79, 40, 902 |
79, 20, 451 |
∴ So the LCM of the given numbers is 2 x 79 x 20 x 451 = 1425160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1425160
Therefore, the GCF of Fractions 97/79,83/40,989/902 is 1/1425160
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 79,40,902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,40,902) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(79,40,902) x common factors =1 x 2 = 2
LCM(79,40,902) = ( 79 × 40 × 902 ) / 2
LCM(79,40,902) = 2850320 / 2
LCM(79,40,902) = 1425160
