So the greatest common factor 67,189,613 is 1.
Lets's calculate LCM of 42,87,991
3 | 42, 87, 991 |
14, 29, 991 |
∴ So the LCM of the given numbers is 3 x 14 x 29 x 991 = 1207038
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1207038
Therefore, the GCF of Fractions 67/42,189/87,613/991 is 1/1207038
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 42,87,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,87,991) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(42,87,991) x common factors =1 x 3 = 3
LCM(42,87,991) = ( 42 × 87 × 991 ) / 3
LCM(42,87,991) = 3621114 / 3
LCM(42,87,991) = 1207038
