Lets's calculate LCM of 15,92,289,983
Given numbers has no common factors except 1. So, there LCM is their product i.e 392040060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/392040060
Therefore, the GCF of Fractions 4/15,40/92,74/289,830/983 is 2/392040060
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 15,92,289,983 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,92,289,983) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(15,92,289,983) x common factors =1 x 1 = 1
LCM(15,92,289,983) = ( 15 × 92 × 289 × 983 ) / 1
LCM(15,92,289,983) = 392040060 / 1
LCM(15,92,289,983) = 392040060
