1,2,449,898
Greatest Common Factor
We found the factors 490,960,898 . The biggest common factor number is the GCF number.
So the greatest common factor 490,960,898 is 2.
Lets's calculate LCM of 58,36,42
2 | 58, 36, 42 |
3 | 29, 18, 21 |
29, 6, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 6 x 7 = 7308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/7308
Therefore, the GCF of Fractions 490/58,960/36,898/42 is 2/7308
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 58,36,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,36,42) = 2
common factors(in case of two or more numbers have common factors) = 6
GCF(58,36,42) x common factors =2 x 6 = 12
LCM(58,36,42) = ( 58 × 36 × 42 ) / 12
LCM(58,36,42) = 87696 / 12
LCM(58,36,42) = 7308
