So the greatest common factor 40,599,678 is 1.
Lets's calculate LCM of 520,896,638
2 | 520, 896, 638 |
2 | 260, 448, 319 |
2 | 130, 224, 319 |
65, 112, 319 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 65 x 112 x 319 = 18578560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18578560
Therefore, the GCF of Fractions 40/520,599/896,678/638 is 1/18578560
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 520,896,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,896,638) = 2
common factors(in case of two or more numbers have common factors) = 8
GCF(520,896,638) x common factors =2 x 8 = 16
LCM(520,896,638) = ( 520 × 896 × 638 ) / 16
LCM(520,896,638) = 297256960 / 16
LCM(520,896,638) = 18578560
