So the greatest common factor 87,49,275 is 1.
Lets's calculate LCM of 297,207,155
3 | 297, 207, 155 |
3 | 99, 69, 155 |
33, 23, 155 |
∴ So the LCM of the given numbers is 3 x 3 x 33 x 23 x 155 = 1058805
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1058805
Therefore, the GCF of Fractions 87/297,49/207,275/155 is 1/1058805
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 297,207,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(297,207,155) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(297,207,155) x common factors =1 x 9 = 9
LCM(297,207,155) = ( 297 × 207 × 155 ) / 9
LCM(297,207,155) = 9529245 / 9
LCM(297,207,155) = 1058805
