Greatest Common Factor
We found the factors 16,776,390 . The biggest common factor number is the GCF number.
So the greatest common factor 16,776,390 is 2.
Lets's calculate LCM of 63,78,396
2 | 63, 78, 396 |
3 | 63, 39, 198 |
3 | 21, 13, 66 |
7, 13, 22 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 13 x 22 = 36036
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/36036
Therefore, the GCF of Fractions 16/63,776/78,390/396 is 2/36036
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 63,78,396 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,78,396) = 3
common factors(in case of two or more numbers have common factors) = 18
GCF(63,78,396) x common factors =3 x 18 = 54
LCM(63,78,396) = ( 63 × 78 × 396 ) / 54
LCM(63,78,396) = 1945944 / 54
LCM(63,78,396) = 36036
