So the greatest common factor 67,88,219 is 1.
Lets's calculate LCM of 490,721,668
2 | 490, 721, 668 |
7 | 245, 721, 334 |
35, 103, 334 |
∴ So the LCM of the given numbers is 2 x 7 x 35 x 103 x 334 = 16856980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16856980
Therefore, the GCF of Fractions 67/490,88/721,219/668 is 1/16856980
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 490,721,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,721,668) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(490,721,668) x common factors =1 x 14 = 14
LCM(490,721,668) = ( 490 × 721 × 668 ) / 14
LCM(490,721,668) = 235997720 / 14
LCM(490,721,668) = 16856980
