So the greatest common factor 42,65,267 is 1.
Lets's calculate LCM of 625,567,135
3 | 625, 567, 135 |
3 | 625, 189, 45 |
3 | 625, 63, 15 |
5 | 625, 21, 5 |
125, 21, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 5 x 125 x 21 x 1 = 354375
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/354375
Therefore, the GCF of Fractions 42/625,65/567,267/135 is 1/354375
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 625,567,135 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(625,567,135) = 1
common factors(in case of two or more numbers have common factors) = 135
GCF(625,567,135) x common factors =1 x 135 = 135
LCM(625,567,135) = ( 625 × 567 × 135 ) / 135
LCM(625,567,135) = 47840625 / 135
LCM(625,567,135) = 354375
