So the greatest common factor 172,528 is 4.
Lets's calculate LCM of 972,225
3 | 972, 225 |
3 | 324, 75 |
108, 25 |
∴ So the LCM of the given numbers is 3 x 3 x 108 x 25 = 24300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/24300
Therefore, the GCF of Fractions 172/972,528/225 is 4/24300
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 972,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(972,225) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(972,225) x common factors =9 x 1 = 9
LCM(972,225) = ( 972 × 225 ) / 9
LCM(972,225) = 218700 / 9
LCM(972,225) = 24300
