So the greatest common factor 38,82,580 is 2.
Lets's calculate LCM of 428,943,216
2 | 428, 943, 216 |
2 | 214, 943, 108 |
107, 943, 54 |
∴ So the LCM of the given numbers is 2 x 2 x 107 x 943 x 54 = 21794616
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/21794616
Therefore, the GCF of Fractions 38/428,82/943,580/216 is 2/21794616
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 428,943,216 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,943,216) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(428,943,216) x common factors =1 x 4 = 4
LCM(428,943,216) = ( 428 × 943 × 216 ) / 4
LCM(428,943,216) = 87178464 / 4
LCM(428,943,216) = 21794616
