Greatest Common Factor
We found the factors 778,145 . The biggest common factor number is the GCF number.
So the greatest common factor 778,145 is 1.
Lets's calculate LCM of 704,387
Given numbers has no common factors except 1. So, there LCM is their product i.e 272448
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/272448
Therefore, the GCF of Fractions 778/704,145/387 is 1/272448
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 704,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(704,387) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(704,387) x common factors =1 x 1 = 1
LCM(704,387) = ( 704 × 387 ) / 1
LCM(704,387) = 272448 / 1
LCM(704,387) = 272448
