Lets's calculate LCM of 28,939,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 20691804
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/20691804
Therefore, the GCF of Fractions 90/28,65/939,580/787 is 5/20691804
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 28,939,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,939,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(28,939,787) x common factors =1 x 1 = 1
LCM(28,939,787) = ( 28 × 939 × 787 ) / 1
LCM(28,939,787) = 20691804 / 1
LCM(28,939,787) = 20691804
