So the greatest common factor 84,804,456 is 12.
Lets's calculate LCM of 48,37,798
2 | 48, 37, 798 |
3 | 24, 37, 399 |
8, 37, 133 |
∴ So the LCM of the given numbers is 2 x 3 x 8 x 37 x 133 = 236208
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/236208
Therefore, the GCF of Fractions 84/48,804/37,456/798 is 12/236208
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 48,37,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,37,798) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(48,37,798) x common factors =1 x 6 = 6
LCM(48,37,798) = ( 48 × 37 × 798 ) / 6
LCM(48,37,798) = 1417248 / 6
LCM(48,37,798) = 236208
