Greatest Common Factor
We found the factors 849,687 . The biggest common factor number is the GCF number.
So the greatest common factor 849,687 is 3.
Lets's calculate LCM of 574,431
Given numbers has no common factors except 1. So, there LCM is their product i.e 247394
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/247394
Therefore, the GCF of Fractions 849/574,687/431 is 3/247394
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 574,431 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(574,431) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(574,431) x common factors =1 x 1 = 1
LCM(574,431) = ( 574 × 431 ) / 1
LCM(574,431) = 247394 / 1
LCM(574,431) = 247394
