Greatest Common Factor
We found the factors 51,61,16,84 . The biggest common factor number is the GCF number.
So the greatest common factor 51,61,16,84 is 1.
Lets's calculate LCM of 67,96,64,249
2 | 67, 96, 64, 249 |
2 | 67, 48, 32, 249 |
2 | 67, 24, 16, 249 |
2 | 67, 12, 8, 249 |
2 | 67, 6, 4, 249 |
3 | 67, 3, 2, 249 |
67, 1, 2, 83 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 3 x 67 x 1 x 2 x 83 = 1067712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1067712
Therefore, the GCF of Fractions 51/67,61/96,16/64,84/249 is 1/1067712
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 67,96,64,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,96,64,249) = 1
common factors(in case of two or more numbers have common factors) = 96
GCF(67,96,64,249) x common factors =1 x 96 = 96
LCM(67,96,64,249) = ( 67 × 96 × 64 × 249 ) / 96
LCM(67,96,64,249) = 102500352 / 96
LCM(67,96,64,249) = 1067712
