Greatest Common Factor
We found the factors 85,63,63,424 . The biggest common factor number is the GCF number.
So the greatest common factor 85,63,63,424 is 1.
Lets's calculate LCM of 64,70,86,64
2 | 64, 70, 86, 64 |
2 | 32, 35, 43, 32 |
2 | 16, 35, 43, 16 |
2 | 8, 35, 43, 8 |
2 | 4, 35, 43, 4 |
2 | 2, 35, 43, 2 |
1, 35, 43, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 2 x 1 x 35 x 43 x 1 = 96320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/96320
Therefore, the GCF of Fractions 85/64,63/70,63/86,424/64 is 1/96320
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 64,70,86,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,70,86,64) = 2
common factors(in case of two or more numbers have common factors) = 128
GCF(64,70,86,64) x common factors =2 x 128 = 256
LCM(64,70,86,64) = ( 64 × 70 × 86 × 64 ) / 256
LCM(64,70,86,64) = 24657920 / 256
LCM(64,70,86,64) = 96320
