So the greatest common factor 46,31,388 is 1.
Lets's calculate LCM of 236,440,855
2 | 236, 440, 855 |
2 | 118, 220, 855 |
5 | 59, 110, 855 |
59, 22, 171 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 59 x 22 x 171 = 4439160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4439160
Therefore, the GCF of Fractions 46/236,31/440,388/855 is 1/4439160
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 236,440,855 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(236,440,855) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(236,440,855) x common factors =1 x 20 = 20
LCM(236,440,855) = ( 236 × 440 × 855 ) / 20
LCM(236,440,855) = 88783200 / 20
LCM(236,440,855) = 4439160
