Lets's calculate LCM of 972,537
3 | 972, 537 |
324, 179 |
∴ So the LCM of the given numbers is 3 x 324 x 179 = 173988
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/173988
Therefore, the GCF of Fractions 415/972,855/537 is 5/173988
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 972,537 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(972,537) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(972,537) x common factors =3 x 1 = 3
LCM(972,537) = ( 972 × 537 ) / 3
LCM(972,537) = 521964 / 3
LCM(972,537) = 173988
