Lets's calculate LCM of 261,524,690
2 | 261, 524, 690 |
3 | 261, 262, 345 |
87, 262, 115 |
∴ So the LCM of the given numbers is 2 x 3 x 87 x 262 x 115 = 15727860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15727860
Therefore, the GCF of Fractions 87/261,450/524,649/690 is 1/15727860
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 261,524,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(261,524,690) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(261,524,690) x common factors =1 x 6 = 6
LCM(261,524,690) = ( 261 × 524 × 690 ) / 6
LCM(261,524,690) = 94367160 / 6
LCM(261,524,690) = 15727860
