Lets's calculate LCM of 767,668,990
2 | 767, 668, 990 |
767, 334, 495 |
∴ So the LCM of the given numbers is 2 x 767 x 334 x 495 = 253616220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/253616220
Therefore, the GCF of Fractions 289/767,463/668,560/990 is 1/253616220
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 767,668,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(767,668,990) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(767,668,990) x common factors =1 x 2 = 2
LCM(767,668,990) = ( 767 × 668 × 990 ) / 2
LCM(767,668,990) = 507232440 / 2
LCM(767,668,990) = 253616220
