1,2,3,6,17,34,51,102
Greatest Common Factor
We found the factors 22,82,67,102 . The biggest common factor number is the GCF number.
So the greatest common factor 22,82,67,102 is 1.
Lets's calculate LCM of 90,51,80,42
2 | 90, 51, 80, 42 |
3 | 45, 51, 40, 21 |
5 | 15, 17, 40, 7 |
3, 17, 8, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 17 x 8 x 7 = 85680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/85680
Therefore, the GCF of Fractions 22/90,82/51,67/80,102/42 is 1/85680
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 90,51,80,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,51,80,42) = 1
common factors(in case of two or more numbers have common factors) = 180
GCF(90,51,80,42) x common factors =1 x 180 = 180
LCM(90,51,80,42) = ( 90 × 51 × 80 × 42 ) / 180
LCM(90,51,80,42) = 15422400 / 180
LCM(90,51,80,42) = 85680
