So the greatest common factor 721,546,357 is 7.
Lets's calculate LCM of 724,411,544
2 | 724, 411, 544 |
2 | 362, 411, 272 |
181, 411, 136 |
∴ So the LCM of the given numbers is 2 x 2 x 181 x 411 x 136 = 40468704
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/40468704
Therefore, the GCF of Fractions 721/724,546/411,357/544 is 7/40468704
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 724,411,544 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(724,411,544) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(724,411,544) x common factors =1 x 4 = 4
LCM(724,411,544) = ( 724 × 411 × 544 ) / 4
LCM(724,411,544) = 161874816 / 4
LCM(724,411,544) = 40468704
