Greatest Common Factor
We found the factors 170,323,809 . The biggest common factor number is the GCF number.
So the greatest common factor 170,323,809 is 1.
Lets's calculate LCM of 238,140,256
2 | 238, 140, 256 |
2 | 119, 70, 128 |
7 | 119, 35, 64 |
17, 5, 64 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 17 x 5 x 64 = 152320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/152320
Therefore, the GCF of Fractions 170/238,323/140,809/256 is 1/152320
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 238,140,256 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(238,140,256) = 2
common factors(in case of two or more numbers have common factors) = 28
GCF(238,140,256) x common factors =2 x 28 = 56
LCM(238,140,256) = ( 238 × 140 × 256 ) / 56
LCM(238,140,256) = 8529920 / 56
LCM(238,140,256) = 152320
