Lets's calculate LCM of 91,900
Given numbers has no common factors except 1. So, there LCM is their product i.e 81900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/81900
Therefore, the GCF of Fractions 357/91,651/900 is 21/81900
Least Common Multiple of 91,900 with GCF Formula
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 91,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,900) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,900) x common factors =1 x 1 = 1
LCM(91,900) = ( 91 × 900 ) / 1
LCM(91,900) = 81900 / 1
LCM(91,900) = 81900
