Greatest Common Factor
We found the factors 38,505,920 . The biggest common factor number is the GCF number.
So the greatest common factor 38,505,920 is 1.
Lets's calculate LCM of 110,600,780
2 | 110, 600, 780 |
2 | 55, 300, 390 |
3 | 55, 150, 195 |
5 | 55, 50, 65 |
11, 10, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 11 x 10 x 13 = 85800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/85800
Therefore, the GCF of Fractions 38/110,505/600,920/780 is 1/85800
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 110,600,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(110,600,780) = 10
common factors(in case of two or more numbers have common factors) = 60
GCF(110,600,780) x common factors =10 x 60 = 600
LCM(110,600,780) = ( 110 × 600 × 780 ) / 600
LCM(110,600,780) = 51480000 / 600
LCM(110,600,780) = 85800
