Lets's calculate LCM of 69,80,408
2 | 69, 80, 408 |
2 | 69, 40, 204 |
2 | 69, 20, 102 |
3 | 69, 10, 51 |
23, 10, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 23 x 10 x 17 = 93840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 35/93840
Therefore, the GCF of Fractions 525/69,175/80,980/408 is 35/93840
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 69,80,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,80,408) = 1
common factors(in case of two or more numbers have common factors) = 24
GCF(69,80,408) x common factors =1 x 24 = 24
LCM(69,80,408) = ( 69 × 80 × 408 ) / 24
LCM(69,80,408) = 2252160 / 24
LCM(69,80,408) = 93840
