So the greatest common factor 630,792,120 is 6.
Lets's calculate LCM of 55,85,387
5 | 55, 85, 387 |
11, 17, 387 |
∴ So the LCM of the given numbers is 5 x 11 x 17 x 387 = 361845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/361845
Therefore, the GCF of Fractions 630/55,792/85,120/387 is 6/361845
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 55,85,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,85,387) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(55,85,387) x common factors =1 x 5 = 5
LCM(55,85,387) = ( 55 × 85 × 387 ) / 5
LCM(55,85,387) = 1809225 / 5
LCM(55,85,387) = 361845
