Lets's calculate LCM of 201,480
3 | 201, 480 |
67, 160 |
∴ So the LCM of the given numbers is 3 x 67 x 160 = 32160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/32160
Therefore, the GCF of Fractions 628/201,442/480 is 2/32160
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 201,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(201,480) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(201,480) x common factors =3 x 1 = 3
LCM(201,480) = ( 201 × 480 ) / 3
LCM(201,480) = 96480 / 3
LCM(201,480) = 32160
