Greatest Common Factor
We found the factors 958,381,670 . The biggest common factor number is the GCF number.
So the greatest common factor 958,381,670 is 1.
Lets's calculate LCM of 85,20,400
2 | 85, 20, 400 |
2 | 85, 10, 200 |
5 | 85, 5, 100 |
17, 1, 20 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 17 x 1 x 20 = 6800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6800
Therefore, the GCF of Fractions 958/85,381/20,670/400 is 1/6800
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 85,20,400 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,20,400) = 5
common factors(in case of two or more numbers have common factors) = 20
GCF(85,20,400) x common factors =5 x 20 = 100
LCM(85,20,400) = ( 85 × 20 × 400 ) / 100
LCM(85,20,400) = 680000 / 100
LCM(85,20,400) = 6800
