Greatest Common Factor
We found the factors 82,13,76,27 . The biggest common factor number is the GCF number.
So the greatest common factor 82,13,76,27 is 1.
Lets's calculate LCM of 31,80,32,64
2 | 31, 80, 32, 64 |
2 | 31, 40, 16, 32 |
2 | 31, 20, 8, 16 |
2 | 31, 10, 4, 8 |
2 | 31, 5, 2, 4 |
31, 5, 1, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 31 x 5 x 1 x 2 = 9920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9920
Therefore, the GCF of Fractions 82/31,13/80,76/32,27/64 is 1/9920
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 31,80,32,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,80,32,64) = 1
common factors(in case of two or more numbers have common factors) = 512
GCF(31,80,32,64) x common factors =1 x 512 = 512
LCM(31,80,32,64) = ( 31 × 80 × 32 × 64 ) / 512
LCM(31,80,32,64) = 5079040 / 512
LCM(31,80,32,64) = 9920
