Greatest Common Factor
We found the factors 45,441,406 . The biggest common factor number is the GCF number.
So the greatest common factor 45,441,406 is 1.
Lets's calculate LCM of 870,800,368
2 | 870, 800, 368 |
2 | 435, 400, 184 |
2 | 435, 200, 92 |
2 | 435, 100, 46 |
5 | 435, 50, 23 |
87, 10, 23 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 87 x 10 x 23 = 1600800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1600800
Therefore, the GCF of Fractions 45/870,441/800,406/368 is 1/1600800
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 870,800,368 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(870,800,368) = 2
common factors(in case of two or more numbers have common factors) = 80
GCF(870,800,368) x common factors =2 x 80 = 160
LCM(870,800,368) = ( 870 × 800 × 368 ) / 160
LCM(870,800,368) = 256128000 / 160
LCM(870,800,368) = 1600800
