:1,19
Now, list down the factors of 31
:1,31
Now, list down the factors of 942
:1,2,3,6,157,314,471,942
Greatest Common Factor
We found the factors 19,31,942 . The biggest common factor number is the GCF number.
So the greatest common factor 19,31,942 is 1.
Lets's calculate LCM of 133,745,869
Given numbers has no common factors except 1. So, there LCM is their product i.e 86104865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/86104865
Therefore, the GCF of Fractions 19/133,31/745,942/869 is 1/86104865
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 133,745,869 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(133,745,869) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(133,745,869) x common factors =1 x 1 = 1
LCM(133,745,869) = ( 133 × 745 × 869 ) / 1
LCM(133,745,869) = 86104865 / 1
LCM(133,745,869) = 86104865
