Greatest Common Factor
We found the factors 5,57,21,385 . The biggest common factor number is the GCF number.
So the greatest common factor 5,57,21,385 is 1.
Lets's calculate LCM of 11,15,751,379
Given numbers has no common factors except 1. So, there LCM is their product i.e 46963785
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/46963785
Therefore, the GCF of Fractions 5/11,57/15,21/751,385/379 is 1/46963785
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 11,15,751,379 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,15,751,379) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(11,15,751,379) x common factors =1 x 1 = 1
LCM(11,15,751,379) = ( 11 × 15 × 751 × 379 ) / 1
LCM(11,15,751,379) = 46963785 / 1
LCM(11,15,751,379) = 46963785
