Lets's calculate LCM of 420,448
2 | 420, 448 |
2 | 210, 224 |
7 | 105, 112 |
15, 16 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 15 x 16 = 6720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6720
Therefore, the GCF of Fractions 525/420,862/448 is 1/6720
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 420,448 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,448) = 28
common factors(in case of two or more numbers have common factors) = 1
GCF(420,448) x common factors =28 x 1 = 28
LCM(420,448) = ( 420 × 448 ) / 28
LCM(420,448) = 188160 / 28
LCM(420,448) = 6720
