So the greatest common factor 19,378,682 is 1.
Lets's calculate LCM of 520,580,842
2 | 520, 580, 842 |
2 | 260, 290, 421 |
5 | 130, 145, 421 |
26, 29, 421 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 26 x 29 x 421 = 6348680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6348680
Therefore, the GCF of Fractions 19/520,378/580,682/842 is 1/6348680
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 520,580,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,580,842) = 2
common factors(in case of two or more numbers have common factors) = 20
GCF(520,580,842) x common factors =2 x 20 = 40
LCM(520,580,842) = ( 520 × 580 × 842 ) / 40
LCM(520,580,842) = 253947200 / 40
LCM(520,580,842) = 6348680
