Lets's calculate LCM of 492,7479
3 | 492, 7479 |
164, 2493 |
∴ So the LCM of the given numbers is 3 x 164 x 2493 = 1226556
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/1226556
Therefore, the GCF of Fractions 128/492,4408/7479 is 8/1226556
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 492,7479 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(492,7479) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(492,7479) x common factors =3 x 1 = 3
LCM(492,7479) = ( 492 × 7479 ) / 3
LCM(492,7479) = 3679668 / 3
LCM(492,7479) = 1226556
