Lets's calculate LCM of 892,432
2 | 892, 432 |
2 | 446, 216 |
223, 108 |
∴ So the LCM of the given numbers is 2 x 2 x 223 x 108 = 96336
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/96336
Therefore, the GCF of Fractions 756/892,406/432 is 14/96336
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 892,432 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(892,432) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(892,432) x common factors =4 x 1 = 4
LCM(892,432) = ( 892 × 432 ) / 4
LCM(892,432) = 385344 / 4
LCM(892,432) = 96336
