Lets's calculate LCM of 428,176
2 | 428, 176 |
2 | 214, 88 |
107, 44 |
∴ So the LCM of the given numbers is 2 x 2 x 107 x 44 = 18832
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18832
Therefore, the GCF of Fractions 634/428,285/176 is 1/18832
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 428,176 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,176) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(428,176) x common factors =4 x 1 = 4
LCM(428,176) = ( 428 × 176 ) / 4
LCM(428,176) = 75328 / 4
LCM(428,176) = 18832
