So the greatest common factor 645,1276 is 1.
Lets's calculate LCM of 704,188
| 2 | 704, 188 |
| 2 | 352, 94 |
| 176, 47 |
∴ So the LCM of the given numbers is 2 x 2 x 176 x 47 = 33088
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33088
Therefore, the GCF of Fractions 645/704,1276/188 is 1/33088
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 704,188 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(704,188) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(704,188) x common factors =4 x 1 = 4
LCM(704,188) = ( 704 × 188 ) / 4
LCM(704,188) = 132352 / 4
LCM(704,188) = 33088
