So the greatest common factor 757,765 is 1.
Lets's calculate LCM of 381,336
3 | 381, 336 |
127, 112 |
∴ So the LCM of the given numbers is 3 x 127 x 112 = 42672
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42672
Therefore, the GCF of Fractions 757/381,765/336 is 1/42672
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 381,336 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(381,336) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(381,336) x common factors =3 x 1 = 3
LCM(381,336) = ( 381 × 336 ) / 3
LCM(381,336) = 128016 / 3
LCM(381,336) = 42672
