So the greatest common factor 84,63,626 is 1.
Lets's calculate LCM of 28,548,928
2 | 28, 548, 928 |
2 | 14, 274, 464 |
7, 137, 232 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 137 x 232 = 889952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/889952
Therefore, the GCF of Fractions 84/28,63/548,626/928 is 1/889952
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 28,548,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,548,928) = 4
common factors(in case of two or more numbers have common factors) = 4
GCF(28,548,928) x common factors =4 x 4 = 16
LCM(28,548,928) = ( 28 × 548 × 928 ) / 16
LCM(28,548,928) = 14239232 / 16
LCM(28,548,928) = 889952
