Lets's calculate LCM of 354,472
2 | 354, 472 |
59 | 177, 236 |
3, 4 |
∴ So the LCM of the given numbers is 2 x 59 x 3 x 4 = 1416
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/1416
Therefore, the GCF of Fractions 238/354,391/472 is 17/1416
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 354,472 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(354,472) = 118
common factors(in case of two or more numbers have common factors) = 1
GCF(354,472) x common factors =118 x 1 = 118
LCM(354,472) = ( 354 × 472 ) / 118
LCM(354,472) = 167088 / 118
LCM(354,472) = 1416
