So the greatest common factor 357,690 is 3.
Lets's calculate LCM of 152,555
Given numbers has no common factors except 1. So, there LCM is their product i.e 84360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/84360
Therefore, the GCF of Fractions 357/152,690/555 is 3/84360
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 152,555 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(152,555) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(152,555) x common factors =1 x 1 = 1
LCM(152,555) = ( 152 × 555 ) / 1
LCM(152,555) = 84360 / 1
LCM(152,555) = 84360
