So the greatest common factor 90,290,680 is 10.
Lets's calculate LCM of 61,56,447
Given numbers has no common factors except 1. So, there LCM is their product i.e 1526952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/1526952
Therefore, the GCF of Fractions 90/61,290/56,680/447 is 10/1526952
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 61,56,447 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,56,447) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,56,447) x common factors =1 x 1 = 1
LCM(61,56,447) = ( 61 × 56 × 447 ) / 1
LCM(61,56,447) = 1526952 / 1
LCM(61,56,447) = 1526952
