So the greatest common factor 684,6850 is 2.
Lets's calculate LCM of 660,8860
2 | 660, 8860 |
2 | 330, 4430 |
5 | 165, 2215 |
33, 443 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 33 x 443 = 292380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/292380
Therefore, the GCF of Fractions 684/660,6850/8860 is 2/292380
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 660,8860 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(660,8860) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(660,8860) x common factors =20 x 1 = 20
LCM(660,8860) = ( 660 × 8860 ) / 20
LCM(660,8860) = 5847600 / 20
LCM(660,8860) = 292380
