Lets's calculate GCF of 640,162
2 | 640, 162 |
320, 81 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 640
:1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Now, list down the factors of 162
:1,2,3,6,9,18,27,54,81,162
Greatest Common Factor
We found the factors 640,162 . The biggest common factor number is the GCF number.
So the greatest common factor 640,162 is 2.
Lets's calculate LCM of 368,103
Given numbers has no common factors except 1. So, there LCM is their product i.e 37904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/37904
Therefore, the GCF of Fractions 640/368,162/103 is 2/37904
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 368,103 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(368,103) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(368,103) x common factors =1 x 1 = 1
LCM(368,103) = ( 368 × 103 ) / 1
LCM(368,103) = 37904 / 1
LCM(368,103) = 37904
