Greatest Common Factor
We found the factors 49,91,161 . The biggest common factor number is the GCF number.
So the greatest common factor 49,91,161 is 7.
Lets's calculate LCM of 644,575,428
2 | 644, 575, 428 |
2 | 322, 575, 214 |
23 | 161, 575, 107 |
7, 25, 107 |
∴ So the LCM of the given numbers is 2 x 2 x 23 x 7 x 25 x 107 = 1722700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/1722700
Therefore, the GCF of Fractions 49/644,91/575,161/428 is 7/1722700
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 644,575,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(644,575,428) = 1
common factors(in case of two or more numbers have common factors) = 92
GCF(644,575,428) x common factors =1 x 92 = 92
LCM(644,575,428) = ( 644 × 575 × 428 ) / 92
LCM(644,575,428) = 158488400 / 92
LCM(644,575,428) = 1722700
