So the greatest common factor 91,98,270 is 1.
Lets's calculate LCM of 613,140,231
7 | 613, 140, 231 |
613, 20, 33 |
∴ So the LCM of the given numbers is 7 x 613 x 20 x 33 = 2832060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2832060
Therefore, the GCF of Fractions 91/613,98/140,270/231 is 1/2832060
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 613,140,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(613,140,231) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(613,140,231) x common factors =1 x 7 = 7
LCM(613,140,231) = ( 613 × 140 × 231 ) / 7
LCM(613,140,231) = 19824420 / 7
LCM(613,140,231) = 2832060
