2 | 256, 512 |
2 | 128, 256 |
2 | 64, 128 |
2 | 32, 64 |
2 | 16, 32 |
2 | 8, 16 |
2 | 4, 8 |
2 | 2, 4 |
1, 2 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 256
Now, list down the factors of 256
:1,2,4,8,16,32,64,128,256
Now, list down the factors of 512
:1,2,4,8,16,32,64,128,256,512
Greatest Common Factor
We found the factors 256,512 . The biggest common factor number is the GCF number.
So the greatest common factor 256,512 is 256.
Lets's calculate LCM of 797,495
Given numbers has no common factors except 1. So, there LCM is their product i.e 394515
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 256/394515
Therefore, the GCF of Fractions 256/797,512/495 is 256/394515
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 797,495 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(797,495) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(797,495) x common factors =1 x 1 = 1
LCM(797,495) = ( 797 × 495 ) / 1
LCM(797,495) = 394515 / 1
LCM(797,495) = 394515
