So the greatest common factor 86,738,720 is 2.
Lets's calculate LCM of 40,80,507
2 | 40, 80, 507 |
2 | 20, 40, 507 |
2 | 10, 20, 507 |
5 | 5, 10, 507 |
1, 2, 507 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 2 x 507 = 40560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/40560
Therefore, the GCF of Fractions 86/40,738/80,720/507 is 2/40560
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 40,80,507 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,80,507) = 1
common factors(in case of two or more numbers have common factors) = 40
GCF(40,80,507) x common factors =1 x 40 = 40
LCM(40,80,507) = ( 40 × 80 × 507 ) / 40
LCM(40,80,507) = 1622400 / 40
LCM(40,80,507) = 40560
