So the greatest common factor 76,88,948 is 4.
Lets's calculate LCM of 479,563,978
Given numbers has no common factors except 1. So, there LCM is their product i.e 263744106
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/263744106
Therefore, the GCF of Fractions 76/479,88/563,948/978 is 4/263744106
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 479,563,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(479,563,978) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(479,563,978) x common factors =1 x 1 = 1
LCM(479,563,978) = ( 479 × 563 × 978 ) / 1
LCM(479,563,978) = 263744106 / 1
LCM(479,563,978) = 263744106
