Lets's calculate LCM of 4475,3575
5 | 4475, 3575 |
5 | 895, 715 |
179, 143 |
∴ So the LCM of the given numbers is 5 x 5 x 179 x 143 = 639925
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/639925
Therefore, the GCF of Fractions 975/4475,987/3575 is 3/639925
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 4475,3575 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(4475,3575) = 25
common factors(in case of two or more numbers have common factors) = 1
GCF(4475,3575) x common factors =25 x 1 = 25
LCM(4475,3575) = ( 4475 × 3575 ) / 25
LCM(4475,3575) = 15998125 / 25
LCM(4475,3575) = 639925
