So the greatest common factor 331,266 is 1.
Lets's calculate LCM of 278,695
139 | 278, 695 |
2, 5 |
∴ So the LCM of the given numbers is 139 x 2 x 5 = 1390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1390
Therefore, the GCF of Fractions 331/278,266/695 is 1/1390
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 278,695 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,695) = 139
common factors(in case of two or more numbers have common factors) = 1
GCF(278,695) x common factors =139 x 1 = 139
LCM(278,695) = ( 278 × 695 ) / 139
LCM(278,695) = 193210 / 139
LCM(278,695) = 1390
