So the greatest common factor 85,55,764 is 1.
Lets's calculate LCM of 306,321,629
3 | 306, 321, 629 |
17 | 102, 107, 629 |
6, 107, 37 |
∴ So the LCM of the given numbers is 3 x 17 x 6 x 107 x 37 = 1211454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1211454
Therefore, the GCF of Fractions 85/306,55/321,764/629 is 1/1211454
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 306,321,629 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(306,321,629) = 1
common factors(in case of two or more numbers have common factors) = 51
GCF(306,321,629) x common factors =1 x 51 = 51
LCM(306,321,629) = ( 306 × 321 × 629 ) / 51
LCM(306,321,629) = 61784154 / 51
LCM(306,321,629) = 1211454
