Lets's calculate LCM of 529,398,941
Given numbers has no common factors except 1. So, there LCM is their product i.e 198120022
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/198120022
Therefore, the GCF of Fractions 63/529,78/398,445/941 is 1/198120022
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 529,398,941 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(529,398,941) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(529,398,941) x common factors =1 x 1 = 1
LCM(529,398,941) = ( 529 × 398 × 941 ) / 1
LCM(529,398,941) = 198120022 / 1
LCM(529,398,941) = 198120022
