So the greatest common factor 694,3492 is 2.
Lets's calculate LCM of 728,312
2 | 728, 312 |
2 | 364, 156 |
2 | 182, 78 |
13 | 91, 39 |
7, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 13 x 7 x 3 = 2184
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2184
Therefore, the GCF of Fractions 694/728,3492/312 is 2/2184
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 728,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(728,312) = 104
common factors(in case of two or more numbers have common factors) = 1
GCF(728,312) x common factors =104 x 1 = 104
LCM(728,312) = ( 728 × 312 ) / 104
LCM(728,312) = 227136 / 104
LCM(728,312) = 2184
