List of positive integer factors of 94 that divides 94 without a remainder.
1,2,47,94
Greatest Common Factor
We found the factors 51,90,11,94 . The biggest common factor number is the GCF number.
So the greatest common factor 51,90,11,94 is 1.
Lets's calculate LCM of 99,78,64,54
2 | 99, 78, 64, 54 |
3 | 99, 39, 32, 27 |
3 | 33, 13, 32, 9 |
11, 13, 32, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 13 x 32 x 3 = 247104
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/247104
Therefore, the GCF of Fractions 51/99,90/78,11/64,94/54 is 1/247104
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 99,78,64,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,78,64,54) = 1
common factors(in case of two or more numbers have common factors) = 108
GCF(99,78,64,54) x common factors =1 x 108 = 108
LCM(99,78,64,54) = ( 99 × 78 × 64 × 54 ) / 108
LCM(99,78,64,54) = 26687232 / 108
LCM(99,78,64,54) = 247104
