:1,2,4,89,178,356
Greatest Common Factor
We found the factors 198,356 . The biggest common factor number is the GCF number.
So the greatest common factor 198,356 is 2.
Lets's calculate LCM of 215,387
43 | 215, 387 |
5, 9 |
∴ So the LCM of the given numbers is 43 x 5 x 9 = 1935
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1935
Therefore, the GCF of Fractions 198/215,356/387 is 2/1935
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 215,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(215,387) = 43
common factors(in case of two or more numbers have common factors) = 1
GCF(215,387) x common factors =43 x 1 = 43
LCM(215,387) = ( 215 × 387 ) / 43
LCM(215,387) = 83205 / 43
LCM(215,387) = 1935
