So the greatest common factor 65,878,451 is 1.
Lets's calculate LCM of 28,63,990
2 | 28, 63, 990 |
3 | 14, 63, 495 |
3 | 14, 21, 165 |
7 | 14, 7, 55 |
2, 1, 55 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 2 x 1 x 55 = 13860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13860
Therefore, the GCF of Fractions 65/28,878/63,451/990 is 1/13860
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 28,63,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,63,990) = 1
common factors(in case of two or more numbers have common factors) = 126
GCF(28,63,990) x common factors =1 x 126 = 126
LCM(28,63,990) = ( 28 × 63 × 990 ) / 126
LCM(28,63,990) = 1746360 / 126
LCM(28,63,990) = 13860
