Lets's calculate LCM of 972,486
2 | 972, 486 |
3 | 486, 243 |
3 | 162, 81 |
3 | 54, 27 |
3 | 18, 9 |
3 | 6, 3 |
2, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 3 x 2 x 1 = 972
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/972
Therefore, the GCF of Fractions 725/972,8180/486 is 5/972
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 972,486 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(972,486) = 486
common factors(in case of two or more numbers have common factors) = 1
GCF(972,486) x common factors =486 x 1 = 486
LCM(972,486) = ( 972 × 486 ) / 486
LCM(972,486) = 472392 / 486
LCM(972,486) = 972
